Note • The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or boardmaterials may be required to maintain the reliability of the assembly. Specified power rating above 125 °C requires dedicated heat-sink pads, which depend on boardmaterials. The given solder pad dimensions reflect the considerations for board design and assembly as outlined e.g. in standards IEC 61188-5-x, or in publication IPC-7351. They do not guarantee any supposed thermal properties, particularly as these are also strongly influenced by many other parameters. Still, the given solder pad dimensions will be found adequate for most general applications, e.g. those referring to “standard operation mode”. Please note however that applications for “power operation mode” or “advanced temperature mode” require special considerations for the design of solder pads and adjacent conductor areas.

MIC2026/2076
The MIC2026/76 are internally current limited and have thermal shutdown that protects the device and load.
The MIC2076 offers “smart” thermal shutdown that reduces current consumption in fault modes. When a thermal shutdown fault occurs, the output is latched off until the faulty load is removed. Removing the load or toggling the enable input will reset the device output.

除了系统损耗和尺寸，滴答声和噼噗声受输入耦合电容Ci 的影响，一个大的输入耦合电容需要更多的电 荷才能到达它的静态电压（1/2VDD）。这些电荷来自经过反馈的内部电路，和有可能产生噼噗声的器件启动 端，因此，在保证低频性能的前提下减小输入电容可以减少启动噼噗声。

构建pc104上的linux系统平台
构建PC104上的嵌入式Linux系统平台构建PC104上的嵌入式Linux系统平台为了适应目前嵌入式系统操作平台在性能、成本、可靠性等各方面的要求，论述了以Linux作为操作系统平台的优势，分析了以PC104卡和CompactFlash卡构造带图形用户界面(GUI)的Linux系统的关键技术.0 前言嵌入式系统的商品化操作系统十分丰富，如Palm OS、VxWorks、pSOS、Neculeus和Windows CE等。
高端嵌入式系统要求许多高级的功能，但其价格也相对昂贵，一般用户难以接受。
微软的Windows CE也有此类功能，却不具备大多数嵌入式系统要求的实时性能，而且难以移植。
Linux为嵌入式系统提供了一个极有吸引力的选择，对于嵌入式系统而言，性能、成本和可靠性是最至关重要的三个因素。
首先，众多文献资料表明，Linux是当前可获得的最简捷、最快速的操作系统，其性能优越之处，是把图形处理为一个用户级的应用，图形可根据需要被选择是否运行。
Linux系统中存在适度复杂的图形界面，但是它们并没有与操作系统的内核紧紧捆绑在一起，图形界面可按需求关闭。
这样就可以在Linux内核上运行专门为嵌入式系统定制的图形系统，从而获得优越的性能。
其次，Linux系统源代码完全公开，可以用非常便宜的价格得到各种Linux分发版，不必考虑许可成本，将用户从许可证的限制中解脱出来，无需去为资金短缺而烦忧。
Linux能正常运行于内存缺乏，容量紧张的系统中，减少在硬件升级上的开支。
另外，在系统稳定性方面，Linux几乎不崩溃，Linux的稳定性是由于它没有像其它操作系统一样内核极其庞大。
考察资料表明，Linux与其它Unix系统和大型操作系统如VMS、IBM大型机等一样具有相同的可靠性。
在上述优势之外，Linux还拥有众多硬件支持的特点和强大的网络支持功能。
正因为Linux在价格、性能、稳定性以及用户定制等方面的突出优势，用它来构建系统操作平台是一个很不错的解决方案。

MICRF506410MHz and 450MHz ISM BandTransceiverGeneral DescriptionThe MICRF506 is a true single-chip, frequency shift keying(FSK) transceiver intended for use in half-duplex,bidirectional RF links. The multi-channeled FSK transceiveris intended for UHF radio equipment in compliance with theEuropean Telecommunication Standard Institute (ETSI)specification, EN300 220.The transmitter consists of a PLL frequency synthesizerand power amplifier. The frequency synthesizer consists ofa voltage-controlled oscillator (VCO), a crystal oscillator,dual modulus prescaler, programmable frequency dividers,and a phase-detector. The loop-filter is external for flexibilityand can be a simple passive circuit. The output power ofthe power amplifier can be programmed to seven levels. Alock-detect circuit detects when the PLL is in lock. Inreceive mode, the PLL synthesizer generates the localoscillator (LO) signal. The N, M, and A values that give theLO frequency are stored in the N0, M0, and A0 registers.The receiver is a zero intermediate frequency (IF) typewhich makes channel filtering possible with low-power,integrated low-pass filters. The receiver consists of a lownoise amplifier (LNA) that drives a quadrature mix pair. Themixer outputs feed two identical signal channels in phasequadrature. Each channel includes a pre-amplifier, a thirdorder Sallen-Key RC low-pass filter that protects thefollowing switched-capacitor filter from strong adjacentchannel signals, and a limiter. The main channel filter is aswitched-capacitor implementation of a six-pole elliptic lowpass filter. The cut-off frequency of the Sallen-Key RC filtercan be programmed to four different frequencies: 100kHz,150kHz, 230kHz, and 340kHz. The I and Q channeloutputs are demodulated and produce a digital data output.The demodulator detects the relative phase of the I and theQ channel signal. If the I channel signal lags behind the Qchannel, the FSK tone frequency is above the LOfrequency (data '1'). If the I channel leads the Q channel,the FSK tone is below the LO frequency (data '0'). Theoutput of the receiver is available on the DataIXO pin. Areceive signal strength indicator (RSSI) circuit indicates thereceived signal level.

Human body model, 1.5k in series with 100pF.4. Specification for packaged product only.5. Guaranteed by design.Programming GeneralThe MICRF506 functions are enab led through a number of programming bits. The programming bits are organized as a set of addressab le control registers, each register holding 8 bits.There are 23 control registers in total in the MICRF506, and they have addresses ranging from 0 to 22. The user can read all the control registers. The user can write to the first 22 registers (0 to 21); the register 22 is a read-only register.All control registers hold 8 bits and all 8 bits must be written to when accessing a control register, or they will be read. Some of the registers do not utilize all 8 bits. The value of an unused bit is “don’t care.”The control register with address 0 is referred to as ControlRegister0, the control register with address 1 is ControlRegister1 and so on. A summary of the control registers is given in the tab le b elow. In addition to the unused bits (marked with”-“) there are a numb er of fixed b its (marked with “0” or “1”). Always maintain these as shown in the table.The control registers in MICRF506 are accessed through a 3-wire interface; clock, data and chip select. These lines are referred to as SCLK, IO, and CS, respectively. This 3-wire interface is dedicated to control register access and is referred to as the control interface. Received data (via RF) and data to transmit (via RF) are handled b y the DataIXO and DatalClk (if enabled) lines; this is referred to as the data interface.The SCLK line is applied externally; access to the control registers are carried out at a rate determined by the user. The MICRF506 will ignore transitions on the SCLK line if the CS line is inactive. The MICRF506 can b e put on a b us, sharing clock and data lines with other devices.All control registers should b e initiated (written to) following a power-on. During operation, however, writing to one register is sufficient to change the way the transceiver works.Adr DataA6…A0D7D6D5D4D3D2D1D0 0000000LNA_by PA2PA1PA0Sync_en Mode1Mode0Load_en 0000001Modulation1Modulation2ol_opamp_en‘0’RSSI_en LD_en PF_FC1PF_FC0 0000010CP_HI‘0’‘0’PA_By OUTS3OUTS2OUTS1OUTS0 0000011‘1’‘1’‘0’VCO_IB2VCO_IB1VCO_IB0VCO_freq1VCO_freq0 0000100Mod_F2Mod_F1Mod_F0Mod_I4Mod_I3Mod_I2Mod_I1Mod_I0 0000101--‘0’‘1’Mod_A3Mod_A2Mod_A1Mod_A0 0000110-Mod_clkS2Mod_clkS1Mod_clkS0BitSync_clkS2BitSync_clkS1BitSync_clkS0BitRate_clkS2 0000111BitRate_clkS1BitRate_clkS0RefClk_K5RefClk_K4RefClk_K3RefClk_K2RefClk_K1RefClk_K0 0001000‘1’ScClk_X2ScClk5ScClk4ScClk3ScClk2ScClk1ScClk0 0001001‘0’‘1’‘1’XCOtune4XCOtune3XCOtune2XCOtune1XCOtune0 0001010--A0_5A0_4A0_3A0_2A0_1A0_0 0001011----N0_11N0_10N0_9N0_8 0001100N0_7N0_6N0_5N0_4N0_3N0_2N0_1N0_0 0001101----M0_11M0_10M0_9M0_8 0001110M0_7M0_6M0_5M0_4M0_3M0_2M0_1M0_0 0001111--A1_5A1_4A1_3A1_2A1_1A1_0 0010000----N1_11N1_10N1_9N1_8 0010001N1_7N1_6N1_5N1_4N1_3N1_2N1_1N1_0 0010010----M1_11M1_10M1_9M1_8 0010011M1_7M1_6M1_5M1_4M1_3M1_2M1_1M1_0 0010100‘1’‘0’‘1’‘1’‘0’‘1’‘0’‘1’0010101----FEEC_3FEEC_2FEEC_1FEEC_0 0010110FEE_7FEE_6FEE_5FEE_4FEE_3FEE_2FEE_1FEE_0Table 1. Control Registers in MICRF506Names of programming bits, unused bits (“-“) and fixed bits (“1” or “0”) are shown. The control register with address 0 is referred to asControlRegister0 etc.Writing to the control registers in MICRF506Writing: A number of octets are entered into MICRF506 followed by a load-signal to activate the new setting. Making these events is referred to as a “write sequence.” It is possible to update all, 1, or n control registers in a write sequence. The address to write to (or the first address to write to) can be any valid address (0-21). The IO line is always an input to the MICRF506 (output from user) when writing. What to write:•The address of the control register to write to (or if more than 1 control register shouldbe written to, the address of the 1st controlregister to write to).• A bit to enable reading or writing of the control registers. This bit is called the R/Wbit.•The values to write into the control register(s).What to write:Field CommentsAddress: A 7-bit field, ranging from 0 to 21. MS B is written first.R/W bit: A 1-bit field, = “0” for writingValues: A number of octets (1-22 octets). MS B in every octet is written first. The first octet iswritten to the control register with thespecified address (=”Address”). The nextoctet (if there is one) is written to the controlregister with address = “Address + 1” and soon.Table 2.How to write:Bring CS active to active to start a write sequence. The active state of the CS line is “high.” Use the S CLK/IO serial interface to clock “Address” and “R/W” bit and “Values” into the MICRF506. MICRF506 will sample the IO line at negative edges of S CLK. Make sure to change the state of the IO line before the negative edge. Refer to figures below.Bring CS inactive to make an internal load-signal and complete the write-sequence. Note: there is an exception to this point. If the programming bit called “load_en” (bit0 in ControlRegister0) is “0”, then no load pulse is generated.The two different ways to “program the chip” are:•Write to a number of control registers (0-22) when the registers have incrementaladdresses (write to 1, all or n registers)•Write to a number of control registers when the registers have non-incrementaladdresses.Writing to a Single RegisterWriting to a control register with address “A6. A5,…A0” is described here. During operation, writing to 1 register is sufficient to change the way the transceiver works. Typical example: Change from receive mode to power-down.What to write:Field CommentsAddress:7 bit = A6, A5, …A0 (A6 = msb. A0 = lsb)R/W bit:“0” for writingValues:8 bits = D7, D6, …D0 (D7 = msb, D0 = lsb)Table 3.“Address” and “R/W bit” together make 1 octet.In addition, 1 octet with programming bits is entered. In total, 2 octets are clocked into the MICRF506.How to write:•Bring CS high•Use SCLK and IO to clock in the 2 octets•Bring CS lowCSIOFigure 1.In Figure 1, IO is changed at positive edges of SCLK. The MICRF506 samples the IO line at negative edges. The value of the R/W bits is always “0” for writing.Writing to All RegistersAfter a power-on, all writable registers should be written. This is described here.Writing to all register can be done at any time. To get the simplest firmware, always write to all registers. The price to pay for the simplicity is increased write-time, which leads to increased time to change the way the MICRF506 works.What to writeField CommentsAddress:‘000000’ (address of the first register to write to, which is 0)R/W bit:“0” for writingValues:1st O c t e t:w a n t e d v a l u e s f o r ControlR egister0. 2nd Octet: wanted valuesfor ControlRegister1 and so on for all of theoctets. So the 22nd octet wants values forControlR egister21. R efer to the specificsections of this document for actual values.Table 4.“Address” and “R/W bit” together make 1 octet.In addition, 22 octets with programming bits are entered. In total, 23 octets are clocked into the MICRF506.How to write:•Bring CS high•Use SCLK and IO to clock in the 23 octets•Bring CS lowRefer to the figure in the next section, “Writing to n registers having incremental addresses”.Writing to n Registers having Incremental AddressesIn addition to entering all bytes, it is also possible to enter a set of n bytes, starting from address i = “A6, A5, … A0”. Typical example: Clock in a new set of frequency dividers (i.e. change the R F frequency).“Incremental addresses”. Registers to be written are located in i, i+1, i+2.What to writeField CommentsAddress:7 bit = A6, A5, …A0 (A6 = msb. A0 = lsb) (address of first byte to write to)R/W bit:“0” for writingValues:n* 8 bits =D7, D6, …D0 (D7 = msb, D0 = lsb) (writtento control reg. with address ”i”)D7, D6, …D0 (D7 = msb, D0 = lsb) (writtento control reg. with address ”i+1”)D7, D6, …D0 (D7 = msb, D0 = lsb) (writtento control reg. with address ”i+n-1”)Table 5.“Address” and “R/W bit” together make 1 octet.In addition, n octets with programming bits are entered. Totally, 1 +n octets are clocked into the MICRF506.How to write:•Bring CS high•Use SCLK and IO to clock in the 1 + n octets•Bring CS lowIn Figure 1, IO is changed at positive edges of SCLK. The MICR F506 samples the IO line at negative edges. The value of the R/W bits is always “0” for writing.CSIOFigure 2.Writing to n Registers having Non-Incremental AddressesR egisters with non-incremental addresses can be written to in one write-sequence as well. Example of non-incremental addresses: “0,1,3”. However, this requires more overhead, and the user should consider the possibility to make a “continuous”update, for example, by writing to “0,1,2,3” (writing the present value of “2” into “2”). The simplest firmware is achieved by always writing to all registers. Refer to previous sections.This write-sequence is divided into several sub-parts:•Disable the generation of load-signals by clearing bit “load_en” (bit0 inControlRegister0)•R epeat for each group of register having incremental addresses:o Bring CS activeo Enter first address for this group,R/W bit and valueso Bring CS inactiveo Finally, enable and make a load-signal by setting “load_en”Refer to the previous sections for how to write to 1 or n (with incremental addresses) registers in the MICRF506.Reading from the control registers in MICRF506 The “read-sequence” is:1.Enter address and R/W bit2.Change direction of IO line3.Read out a number of octets and change IOdirection back again.It is possible to read all, 1 or n registers. The address to read from (or the first address to read from) can be any valid address (0-22). R eading is not destructive, i.e. values are not changed. The IO line is output from the MICRF506 (input to user) for a part of the read-sequence. R efer to procedure description below.A read-sequence is described for reading n registers, where n is number 1-23.Reading n registers from MICRF506CSIOIO InputIO OutputFigure 3.In the figure, 1 register is read. The address is A6,A5, … A0. A6 = msb. The data read out is D7, D6,…D0. The value of the R/W bit is always “1” for reading.SCLK and IO together form a serial interface. SCLKis applied externally for reading as well as for writing.•Bring CS active•Enter address to read from (or the first address to read from) (7 bits) and•The R/W bit = 1 to enable reading•Make the IO line an input to the user (set pin in tristate)•Read n octets. The first rising edge of SCLK will set the IO as an output from theMICRF506. MICRF will change the IO line atpositive edges. The user should read the IOline at the negative edges.•Make the IO line an output from the user again.Programming interface timingFigure 4 and Table 6 shows the timing specification for the3-wire serial programming interface.CSSCLKIO A6A5A0RW D7D6D2D1D0Address Register Data RegisterLOADTsclTwriteTreadThighTlowTperTcsr traisetfallFigure 4.ValuesSymbol Parameter Min.Typ.Max.Units Tper Min. period ofSCLK50nsThigh Min. high time ofSCLK20nsTlow Min. low time ofSCLK20nstfall Max. time offalling edge ofSCLK1nstrise Max. time of risingedge of SCLK1nsTcsr Max. time of risingedge of CS tofalling edge ofSCLK0nsTcsf Min. delay fromrising edge of CSto rising edge ofSCLK5nsTwrite Min. delay fromvalid IO to fallingedge of SCLKduring a writeoperation0nsTread Min. delay fromrising edge ofSCLK to valid IOduring a readoperation(assuming loadcapacitance of IOis 25pF)75nsTable 6.

The loop-filter is external for flexibility and can be a simple passive circuit. The lengths of the N, M, and A registers are12, 12 and 6 respectively. The M, N, and A values can be calculated from the formula:fPDH =f XCO M =f VCO 31 N +A =f RF 431 N +Awhere fPhD is the phase detector comparison frequency.PhD: Phase detector comparison frequency fxco: Crystal oscillator frequencyfvco: Voltage controlled oscillator frequencyThere are two sets of each of the divide factors (i.e.A0 and A1). If modulation by using the dividers is selected (that is Modulation1=1, Modulation0=0), the two sets should be programmed to give two RF frequencies, separated by two times the specified frequency deviation. For all other modulation methods, and also in receive mode, the 0-set will be used.Crystal Oscillator (XCO)Adr D7D6D5D4D3D2D1D00001001‘0’‘1’‘1’XCOtune4XCOtune3XCOtune2XCOtune1XCOtune0The crystal oscillator is a very critical block. As the crystal oscillator is a reference for the RF output frequency and also for the LO frequency in the receiver, very good phase and frequency stability is required. The schematic of the crystal oscillator’sexternal components for 16MHz are shown in Figure 5.XT Figure 5. Crystal Oscillator CircuitThe crystal should be connected between pins XosIn and XoscOut (pin 23 and 23). In addition,loading capacitors for the crystal are required. The loading capacitor values depend on the total load capacitance, C L , specified for the crystal. The load capacitance seen between the crystal terminals should be equal to C L for the crystal to oscillate at the specified frequency.C L =11C 10+1C 11+C parasiticThe parasitic capacitance is the pin input capacitance and PCB stray capacitance. Typically,the total parasitic capacitance is around 6pF. For instance, for a 9pF load crystal the recommended values of the external load capacitors are 5.6pF.It is also possible to tune the crystal oscillator internally by switching in internal capacitance using 5 tune bits XCOtune4 – XCOtun0. When XCOtune4– XCOtune0 = 0 no internal capacitors are connected to the crystal pins. When XCOtune4 –XCOtune0 = 1 all of the internal capacitors are connected to the crystal pins. Figure 3 shows the tuning range for two different capacitor values, there are 1.5pF and no capacitors.The crystal used is a TN4-26011 from Toyocom.S pecification: Package TSX-10A, Nominal frequency16.000000 MHz, frequency tolerance ±10ppm,frequency stability ±9ppm, load capacitance 9pF,pulling sensitivity 15ppm/pF.-60,0-40,0-20,00,020,040,060,080,0100,008162432XCO bitvalue[p p m ]Figure 6.

VCO Bit SettingT he bias bit will optimize the phase noise, and the frequency bit will control a capacitor bank in the VCO. T he tuning range, the RF frequency versus varactor voltage, is dependent on the VCO frequency setting, and can be shown in Figure 7.When the tuning voltage is in the range from 0.9V to 1.4V, the VCO gain is at its maximum, approximately 32 to 35MHz/V. It is recommended that the varactor voltage stays in this range.T he input capacitance at the varactor pin must be taken into consideration when designing the PLL loop filter. This is most critical when designing a loop filter with high bandwidth, which gives relatively small component values. T he input capacitance isapproximately 6pF.Figure 7.

MIC45205评估板：26V 6A DC-到-DC电源模块，超轻负载和超速控制是Micrel公司的
MIC45205 Evaluation Board26V/6A DC-to-DC Power ModuleGeneral DescriptionMicrel’s MIC45205 is a synchronous step-down regulatormodule, featuring a unique adaptive ON-time controlarchitecture. The module incorporates a DC-to-DCcontroller, power MOSFETs, bootstrap diode, bootstrapcapacitor, and an inductor in a single package; simplifyingthe design and layout process for the end user.This highly integrated solution expedites system designand improves product time-to-market. The internalMOSFETs and inductor are optimized to achieve highefficiency at a low output voltage. The fully optimizeddesign can deliver up to 6A current under a wide inputvoltage range of 4.5V to 26V, without requiring additionalcooling.The MIC45205-1 uses Micrel’s HyperLight Load®(HLL)MIC45205-2 uses Micrel’s Hyper Speed Control™architecture which enables ultra-fast load transientresponse, allowing for a reduction of output capacitance.The MIC45205 offers 1% output accuracy that can beadjusted from 0.8V to 5.5V with two external resistors.The basic parameters of the evaluation board are:•Input: 4.5V to 26V•Output 0.8V to 5V at 6A•600kHz Switching Frequency−Adjustable 200kHz to 600kHzDatasheets and support documentation are available onMicrel’s web site at: .RequirementsThe MIC45205-1 and MIC45205-2 evaluation boardrequires only a single power supply with at least 10Acurrent capability. No external linear regulator is requiredto power the internal biasing of the IC because theMIC45205 has an internal PVDD LDO. In the applicationswith VIN < +5.5V, PVDD should be tied to VIN to bypassthe internal linear regulator. The output load can either bea passive or an active load.PrecautionsThe MIC45205 evaluation board does not have reversepolarity protection. Applying a negative voltage to the VINand GND terminals may damage the device. Themaximum VIN of the board is rated at 26V. Exceeding 30Von the VIN could damage the device.Getting Started1. VIN SupplyConnect a supply to the VIN and GND terminals,paying careful attention to the polarity and the supplyrange (4.5V < VIN < 26V). Monitor IIN with a currentmeter and monitor input voltage at VIN and GNDterminals with a voltmeter. Do not apply power untilStep 4.2. Connect Load and Monitor OutputConnect a load to the VOUT and GND terminals. Theload can be either a passive (resistive) or an active (asin an electronic load) type. A current meter may beplaced between the VOUT terminal and load tomonitor the output current. Ensure the output voltageis monitored at the VOUT terminal.3. Enable InputThe EN pin has an on board 100kΩpull-up resistor(R10) to VIN, which allows the output to be turned onwhen PVDD exceeds its UVLO threshold. An ENconnector is provided on the evaluation board forusers to easily access the enable feature. Applying anexternal logic signal on the EN pin to pull it low orusing a jumper to short the EN pin to GND will shut offthe output of the MIC45205 evaluation board.4. Turn PowerTurn on the VIN supply and verify that the outputvoltage is regulated to 5V.Ordering InformationPart Number DescriptionMIC45205-1YMP EV MIC45205-1 Evaluation BoardMIC45205-2YMP EV MIC45205-2 Evaluation BoardFeaturesFeedback ResistorsThe output voltage on the MIC45205 evaluation board, which is preset to 5.0V, is determined by the feedback divider, as illustrated in Equation 1:+×=BOTTOMREF OUT R R141V V Eq. 1where V REF = 0.8V, and R BOTTOM is one of R3 thru R9. Leaving the R BOTTOM open by removing all jumpers on the feedback headers gives a 0.8V output voltage. All other voltages not listed above can be set by modifying R BOTTOM value according to Equation 2:REFOUT REFBOTTOM V V V R1R −×=Eq. 2Note that the output voltage should not be set to exceed 5V.Table 1.

MIC45205 Current-Limiting CircuitIn each switching cycle of the MIC45205, the inductor current is sensed by monitoring the low-side MOSFET in the OFF period. The sensed voltage V(ILIM)is compared with the power ground (PGND) after a blanking time of 150ns. In this way the drop voltage over the resistor R15 (V CL) is compared with the drop over the bottom FET generating the short current limit. The small capacitor (C15) connected from ILIM pin to PGND filters the switching node ringing during the off-time allowing a better short-limit measurement. The time constant created by R15 and C15 should be much less than the minimum off time.The V CL drop allows programming of short limit through the value of the resistor (R15) if the absolute value of the voltage drop on the bottom FET is greater than V CL. In that case the V(ILIM)is lower than PGND and a short circuit event is triggered. A hiccup cycle to treat the short event is generated. The hiccup sequence including the soft-start reduces the stress on the switching FETs and protects the load and supply for severe short conditions. The short-circuit current limit can be programmed by using Equation 3:()CLCL)ON(DSPPLCLIMIVR)5.0II(R15+××D−=Eq. 3 where:I CLIM = Desired current limitR DS(ON) = On-resistance of low-side power MOSFET, 16mΩ typicallyV CL= Current-limit threshold (typical absolute value is 14mV per Electrical Characteristics in the MIC45205 data sheet)I CL= Current-limit source current (typical value is 80µA, per Electrical Characteristics in the MIC45205 data sheet). ΔI L(PP)= Inductor current peak-to-peak, since the inductor is integrated, use Equation 4 to calculate the inductor ripple current.The peak-to-peak inductor current ripple is:LfV)V(VVIswIN(MAX)OUTIN(MAX)OUTL(PP)××−×=D Eq. 4The MIC45205 has 1.0µH inductor integrated into the module. In case of hard short, the short limit is folded down to allow an indefinite hard short on the output without any destructive effect. It is mandatory to make sure that the inductor current used to charge the output capacitance during soft start is under the folded short limit; otherwise the supply will go in hiccup mode and may not be finishing the soft start successfully.The MOSFET R DS(ON) varies 30 to 40% with temperature. Therefore, it is recommended to add a 50% margin to I CLIM in the above equation to avoid false current limiting due to increased MOSFET junction temperature rise. With R15 = 1.37kΩ and C15 = 15pF, the typical output current limit is 8A.Setting the Switching FrequencyThe MIC45205 switching frequency can be adjusted by changing the value of resistors R1 and R2. The switching frequency also depends on VIN, V OUT and load conditions.Figure 2.

Forcing the enable pin low disables the regulator and sends it into a “zero” off-mode-current state. In this state, current consumed by the regulator goes nearly to zero. Forcing the enable pin high enables the output voltage. This part is CMOS and the enable pin cannot be left floating; a floating enable pin may cause an indetermi-nate state on the output.Input CapacitorAn input capacitor is not required for stability. A 1µF input capacitor is recommended when the bulk ac supply capaci-tance is more than 10 inches away from the device, or when the supply is a battery.Output CapacitorThe MIC5246 requires an output capacitor for stability. The design requires 1µF or greater on the output to maintain stability. The capacitor can be a low-ESR ceramic chip capacitor. The MIC5246 has been designed to work specifi-cally with the low-cost, small chip capacitors. Tantalum capacitors can also be used for improved capacitance over temperature. The value of the capacitor can be increased without bound.X7R dielectric ceramic capacitors are recommended be-cause of their temperature performance. X7R-type capaci-tors change capacitance by 15% over their operating tem-perature range and are the most stable type of ceramic capacitors. Z5U and Y5V dielectric capacitors change value by as much 50% and 60% respectively over their operating temperature ranges. To use a ceramic chip capacitor with Y5V dielectric, the value must be much higher than an X7R ceramic or a tantalum capacitor to ensure the same minimum capacitance value over the operating temperature range. Tantalum capacitors have a very stable dielectric (10% over their operating temperature range) and can also be used with this device.Error FlagThe error flag output is an active-low, open-drain output that drives low when a fault condition AND an undervoltage detection occurs. Internal circuitry intelligently monitors overcurrent, overtemperature and dropout conditions and ORs these outputs together to indicate some fault condition. The output of that OR gate is ANDed with an output voltage monitor that detects an undervoltage condition. That output drives the open-drain transistor to indicate a fault. This prevents chattering or inadvertent triggering of the error flag. The error flag must be pulled up using a resistor from the flag pin to either the input or the output.Error Flag CircuitThe error flag circuit was designed essentially to work with a capacitor to ground to act as a power-on reset generator, signaling a power-good situation once the regulated voltage was up and/or out of a fault condition. This capacitor delays the error signal from pulling high, allowing the downstream circuits time to stabilize. When the error flag is pulled up to the input without using a pull-down capacitor, then there can be a glitch on the error flag upon start up of the device. This is due to the response time of the error flag circuit as the device starts up. When the device comes out of the zero off mode current state, all the various nodes of the circuit power up before the device begins supplying full current to the output capacitor. The error flag drives low immediately and then releases after a few microseconds. The intelligent circuit that triggers an error detects the output going into current limit AND the output being low while charging the output capacitor. The error output then pulls low for the duration of the turn-on time. This glitch is filtered by putting a capacitor from the error flag to ground. The glitch does not occur if the error flag pulled up to the output.Transient ResponseThe MIC5246 implements a unique output stage to dramati-cally improve transient response recovery time. The output is a totem-pole configuration with a P-channel MOSFET pass device and an N-channel MOSFET clamp. The N-channel clamp is a significantly smaller device that prevents the output voltage from overshooting when a heavy load is removed. This feature helps to speed up the transient re-sponse by significantly decreasing transient response recov-ery time during the transition from heavy load (100mA) to light load (85µA).Active ShutdownThe MIC5246 also features an active shutdown clamp, which is an N-channel MOSFET that turns on when the device is disabled. This allows the output capacitor and load to dis-charge, de-energizing the load.Thermal ConsiderationsThe MIC5246 is designed to provide 150mA of continuous current in a very small package. Maximum power dissipation can be calculated based on the output current and the voltage drop across the part. To determine the maximum power dissipation of the package, use the junction-to-ambient ther-mal resistance of the device and the following basic equation: PT TD(max)J(max)AJA=−θT J(max) is the maximum junction temperature of the die, 125°C, and T A is the ambient operating temperature. θJA is layout dependent; Table 1 shows examples of junction-to-ambient thermal resistance for the MIC5246.PackageθJA RecommendedθJA 1" SquareθJCMinimum Footprint Copper CladSOT-23-5 (M5)235°C/W185°C/W145°C/W Table 1.SOT-23-5 Thermal ResistanceMIC5246Micrel The actual power dissipation of the regulator circuit can bedetermined using the equation:P D = (V IN– V OUT) I OUT + V IN I GNDSubstituting P D(max) for P D and solving for the operatingconditions that are critical to the application will give themaximum operating conditions for the regulator circuit. Forexample, when operating the MIC5246-3.0BM5 at 50°C witha minimum footprint layout, the maximum input voltage for aset output current can be determined as follows:P 125C5C 235C/WD(max)=°−°°P D(max) = 315mWThe junction-to-ambient thermal resistance for the minimum footprint is 235°C/W, from Table 1. The maximum power dissipation must not be exceeded for proper operation. Using the output voltage of 3.0V and an output current of 150mA, the maximum input voltage can be determined. Because this device is CMOS and the ground current is typically 100µA over the load range, the power dissipation contributed by the ground current is < 1% and can be ignored for this calculation.315mW = (V IN– 3.0V)150mA315mW = V IN·150mA – 450mW810mW = V IN·150mAV IN(max) = 5.4VTherefore, a 3.0V application at 150mA of output current can accept a maximum input voltage of 5.4V in a SOT-23-5 package. For a full discussion of heat sinking and thermal effects on voltage regulators, refer to the Regulator Thermals section of Micrel’s Designing with Low-Dropout Voltage Regu-lators handbook.Fixed Regulator ApplicationsFFigure 1. Low-Noise Fixed Voltage Application Figure 1 shows a standard low-noise configuration with a 47kΩ pull-up resistor from the error flag to the input voltage and a pull-down capacitor to ground for the purpose of fault indication.Dual-Supply OperationWhen used in dual supply systems where the regulator load is returned to a negative supply, the output voltage must be diode clamped to ground.MIC5246Micrel Package InformationSOT-23-5 (M)MIC5246MicrelMIC5246Micrel June 200011MIC5246MIC5246MicrelMICREL INC.1849 FORTUNE DRIVE SAN JOSE, CA95131USATEL + 1 (408) 944-0800 FAX + 1 (408) 944-0970 WEB This information is believed to be accurate and reliable, however no responsibility is assumed by Micrel for its use nor for any infringement of patents or other rights of third parties resulting from its use.

MIC5206
150mA Low-Noise LDO Regulator
General Description
The MIC5206 is an efficient linear voltage regulator with very low dropout voltage (typically 17mV at light loads and 165mV at 150mA), and very low ground current (600µA at 100mA output), with better than 1% initial accuracy. It has a logic compatible enable/shutdown control input and an internal undervoltage monitor. Designed especially for hand-held, battery-powered devices, the MIC5206 can be switched by a CMOS or TTL compatible logic signal. When disabled, power consumption drops nearly to zero. Dropout ground current is minimized to prolong battery life. Key features include an undervoltage monitor with an error flag output, a reference bypass pin to improve its already lownoise performance (8-lead versions only), reversed-battery protection, current limiting, and overtemperature shutdown. The MIC5206 is available in several fixed voltages in a tiny SOT-23-5 package. It features a pinout, similar to the LP2980, but has significantly better performance. Fixed and adjustable output voltage versions, featuring the reference bypass option, are available in the 8-lead Micrel Mini 8™ 8-lead MSOP (micro small-outline package).
