MAX8510 MAX8511 MAX8512 极低噪声、低掉电的线性调压器说明说明书

General DescriptionThe MAX8510/MAX8511/MAX8512 ultra-low-noise, low-dropout (LDO) linear regulators are designed to deliver up to 120mA continuous output current. These regulators achieve a low 120mV dropout for 120mA load current. The MAX8510 uses an advanced architecture to achieve ultra-low output voltage noise of 11μV RMS and PSRR of 54dB at 100kHz.The MAX8511 does not require a bypass capacitor, hence achieving the smallest PC board area. The MAX8512’s output voltage can be adjusted with an external divider.The MAX8510/MAX8511 are preset to a variety of voltag-es in the 1.5V to 4.5V range. Designed with a P-channel MOSFET series pass transistor, the MAX8510/MAX8511/MAX8512 maintain very low ground current (40μA).The regulators are designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8510 requires only 1μF (typ) of output capacitance for stability with any load. When disabled, current consumption drops to below 1μA.Package options include a 5-pin SC70 and a tiny 2mm x 2mm x 0.8mm TDFN package.Applications●Cellular and Cordless Phones ●PDA and Palmtop Computers ●Base Stations●Bluetooth Portable Radios and Accessories ●Wireless LANs ●Digital Cameras ●Personal Stereos●Portable and Battery-Powered EquipmentFeatures●Space-Saving SC70 and TDFN (2mm x 2mm) Packages ●11μV RMS Output Noise at 100Hz to 100kHzBandwidth (MAX8510)●78dB PSRR at 1kHz (MAX8510) ●120mV Dropout at 120mA Load●Stable with 1μF Ceramic Capacitor for Any Load ●Guaranteed 120mA Output●Only Need Input and Output Capacitors (MAX8511) ●Output Voltages: 1.5V, 1.8V, 2.5V, 2.6V, 2.7V, 2.8V,2.85V, 3V,3.3V,4.5V (MAX8510/MAX8511) and Adjustable (MAX8512) ●Low 40μA Ground Current ●Excellent Load/Line Transient●Overcurrent and Thermal Protection19-2732; Rev 5; 5/19Output Voltage Selector Guide appears at end of data sheet.Ordering Information continued at end of data sheet.*xy is the output voltage code (see Output Voltage Selector Guide).

The parts are available with preset output voltages ranging from 1.5V to 4.5V in 100mV increments. These devices can supply loads up to 120mA. As shown in the Functional Diagram , the MAX8510/MAX8511 consist of an innovative bandgap core and noise bypass circuit, error amplifier, P-channel pass transistor, and internal feedback voltage-divider. The MAX8512 allows for adjustable output with an external feedback network.The 1.225V bandgap reference is connected to the error amplifier’s inverting input. The error amplifier compares this reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the refer-ence voltage, the pass-transistor gate is pulled low. This allows more current to pass to the output and increases the output voltage. If the feedback voltage is too high, the pass transistor gate is pulled high, allowing less cur-rent to pass to the output. The output voltage is fed back through an internal resistor voltage-divider connected to the OUT pin.An external bypass capacitor connected to BP (MAX8510) reduces noise at the output. Additional blocks include a current limiter, thermal sensor, and shutdown logic.Internal P-Channel Pass TransistorThe MAX8510/MAX8511/MAX8512 feature a 1Ω (typ) P-channel MOSFET pass transistor. This provides sev-eral advantages over similar designs using a PNP pass transistor, including longer battery life. The P-channel MOSFET requires no base drive, which considerably reduces quiescent current. PNP-based regulators waste considerable current in dropout when the pass transistor saturates. They also use high base-drive current under heavy loads. The MAX8510/MAX8511/MAX8512 do not suffer from these problems and consume only 40μA of quiescent current in light load and 220μA in dropout (see the Typical Operating Characteristics ).Output Voltage SelectionThe MAX8510/MAX8511 are supplied with factory-set output voltages from 1.5V to 4.5V, in 100mV increments (see Ordering Information ). The MAX8512 features a user-adjustable output through an external feedback net-work (see the Typical Operating Circuits ).To set the output of the MAX8512, use the following equa-tion:OUT REF V R1R2X -1V=where R2 is chosen to be less than 240kΩ and V REF = 1.225V. Use 1% or better resistors.PINNAMEFUNCTIONMAX8510MAX8511MAX8512SC70TDFN -EP SC70TDFN -EP SC70TDFN -EP 151515IN Unregulated Input Supply 232323GNDGround343434SHDN Shutdown.

Driving SHDN low disables the voltage reference, error amplifier, gate-drive circuitry, and pass transistor (see the Functional Diagram), and the device output enters a high-impedance state. Connect SHDN to IN for normal operation.Current LimitThe MAX8510/MAX8511/MAX8512 include a current lim-iter, which monitors and controls the pass transistor’s gate voltage, limiting the output current to 200mA. For design purposes, consider the current limit to be 130mA (min) to 300mA (max). The output can be shorted to ground for an indefinite amount of time without damaging the part. Thermal-Overload ProtectionThermal-overload protection limits total power dissipation in the MAX8510/MAX8511/MAX8512. When the junction temperature exceeds T J = +160°C, the thermal sensor signals the shutdown logic, turning off the pass transis-tor and allowing the IC to cool down. The thermal sensor turns the pass transistor on again after the IC’s junction temperature drops by 10°C, resulting in a pulsed output during continuous thermal-overload conditions.Thermal-overload protection is designed to protect the MAX8510/MAX8511/MAX8512 in the event of a fault con-dition. For continual operation, do not exceed the abso-lute maximum junction temperature rating of T J = +150°C. Operating Region and Power DissipationThe MAX8510/MAX8511/MAX8512 maximum power dis-sipation depends on the thermal resistance of the case and circuit board, the temperature difference between the die junction and ambient, and the rate of airflow. The power dissipation across the device is:P = I OUT (V IN - V OUT)The maximum power dissipation is:P MAX = (T J - T A) / (θJC + θCA)where T J - T A is the temperature difference between the MAX8510/MAX8511/MAX8512 die junction and the sur-rounding air, θJC is the thermal resistance of the package, and θCA is the thermal resistance through the PC board, copper traces, and other materials to the surrounding air. The GND pin of the MAX8510/MAX8511/MAX8512 per-forms the dual function of providing an electrical connec-tion to ground and channeling heat away. Connect the GND pin to ground using a large pad or ground plane.Noise ReductionFor the MAX8510, an external 0.01μF bypass capaci-tor between BP and OUT with innovative noise bypass scheme reduces output noises dramatically, exhibiting 11μV RMS of output voltage noise with C BP = 0.01μF and C OUT = 1μF. Startup time is minimized by a poweron cir-cuit that precharges the bypass capacitor. Applications InformationCapacitor Selectionand Regulator StabilityUse a 1μF capacitor on the MAX8510/MAX8511/MAX8512 input and a 1μF capacitor on the output. Larger input capacitor values and lower ESRs provide better noise rejection and line-transient response. Reduce output noise and improve load-transient response, stability, and power-supply rejection by using large output capacitors. Note that some ceramic dielectrics exhibit large capaci-tance and ESR variation with temperature. With dielec-trics such as Z5U and Y5V, it may be necessary to use a 2.2μF or larger output capacitor to ensure stability at temperatures below -10°C. With X7R or X5R dielectrics, 1μF is sufficient at all operating temperatures. A graph of the region of stable C OUT ESR vs. load current is shown in the Typical Operating Characteristics.Use a 0.01μF bypass capacitor at BP (MAX8510) for low-output voltage noise. The leakage current going into the BP pin should be less than 10nA. Increasing the capaci-tance slightly decreases the output noise. Values above 0.1μF and below 0.001μF are not recommended. Noise, PSRR, and Transient ResponseThe MAX8510/MAX8511/MAX8512 are designed to deliv-er ultra-low noise and high PSRR, as well as low dropout and low quiescent currents in battery-powered systems. The MAX8510 power-supply rejection is 78dB at 1kHz and 54dB at 100kHz. The MAX8511/MAX8512 PSRR is 72dB at 1kHz and 46dB at 100kHz (see the Power-Supply Rejection Ratio vs. Frequency graph in the Typical Operating Characteristics).When operating from sources other than batteries, improved supply-noise rejection and transient response can be achieved by increasing the values of the input and output bypass capacitors, and through passive filter-ing techniques. The Typical Operating Characteristics show the MAX8510/MAX8511/MAX8512 line- and load-transient responses.MAX8512Low-Dropout, 120mA Linear RegulatorsDropout VoltageA regulator’s minimum dropout voltage determines the lowest usable supply voltage. In battery-powered sys-tems, this determines the useful end-of-life battery volt-age. Because the MAX8510/MAX8511/MAX8512 use aP-channel MOSFET pass transistor, their dropout voltage is a function of drain-to-source on-resistance (RDS(ON)) multiplied by the load current (see the Typical Operating Characteristics ).MAX8512Low-Dropout, 120mA Linear RegulatorsFunctional Diagram*xy is the output voltage code (see Output Voltage Selector Guide).

The device provides power solution for products powered by a one-cell Lithium-Ion or multi-cell alkaline battery applications where the output voltage is within battery voltage range.The MP2155 uses a current mode, fixed frequency PWM control for optimal stability and transient response. The fixed 1MHz switching frequency and integrated low R DS(ON) N-channel and P-channel MOSFETs minimize the solution footprint while maintaining high efficiency.To ensure the longest battery life MP2155 has an optional pulse skipping mode that reduces switching frequency under light load conditions. For other low noise applications where variable frequency power save mode may cause interference, the logic control input MODE pin forces fixed frequency PWM operation under all load conditions.The MP2155 operates with input voltage from 2V to 5.5V to provide adjustable output voltage (1.5V to 5V).

When the MODE pin is held high, the MP2155 operates in constant-frequency PWM mode with peak current mode control. As shown in Figure 1, the output voltage is sensed via the FB pin through an external resistor-divider from the output to ground. The voltage difference between FB pin and the internal reference is amplified by error amplifier to generate control signal V C-Buck . By comparing V C-Buck with internal compensation ramp (the sensed SWA’s current with slope compensation) through Buck comparator, a PWM control signal for PWM buck mode is outputted. Another control signal V C-Boost is derived from V C-Buck through level shift. Similarly, V C-Boost compares with the same ramp signal through Boost comparator and generates the PWM control signal for PWM boost mode. The switch topology for the buck-boost converter is shown in Figure 2.Figure 2—Buck-Boost Switch TopologyBuck Region (Vin > Vout)When the input voltage is significantly greater than output voltage, which means the converter can deliver energy to load within the maximum duty cycle of SWA, so the converter operates in buck mode. The control signal V C-Boost is always lower than compensation ramp because Buck can deliver enough energy to load, thus switch D turns on constantly and switch C remains off. Meanwhile, V C-Buck compares with compensation ramp normally and generates PWM signal, therefore, switches A and B are pulse-width-modulated to produce the required duty cycle to support the output voltage.Buck-Boost Region (Vin ≈ Vout)When Vin is close to Vout, due to duty cycle limit of SWA the converter isn’t able to provide wanted energy to load. In this case SWA will be turned on over all the period, that is, there is no BD operation(SWB and SWD being turned on simultaneously). Now a new period begins. Since there is no BD in last period, an offset voltage is added to the ramp signal to make the ramp signal easily hit V C-Buck . At the same time due to loop regulation V C-Boost (as well as V C-Buck ) rises to some level, so that the ramp signal can intersect it to produce the PWM driving signal for Boost operation. After SWC is turned off the ramp signal continues rising (the actual inductor current may rise or fall depending on the difference between Vin and Vout), when the ramp intersects V C-Buck , PWM signal for Buck operation then is generated . Now the buck’s duty cycle is within its limit, so there is BD operation in current period, which means next period the offset voltage will be removed. This is the so-called buck-boost region. With heavy load due to voltage drop on switches the actual input range for this region may be a little wide.Boost Region (Vin < Vout)When the input voltage is significantly lower thanoutput voltage, the converter operates in boost mode. The control signal V C-Buck is always higher than compensation ramp even with the offset voltage always added, thus switch A turns on continuously and switch B remains off. Meanwhile, V C-Boost compares compensation ramp normally and generates PWM signal, therefore, switches C and D are pulse-width-modulated to produce the required duty cycle to support the output regulation voltage.PSMWhen Mode Pin is pulled down below the low level threshold, the MP2155 will automatically enter PSM if load is light. When working in PSM, a train of SW pulses are initiated by a Boost operation, and ended with BD operation. During this process, SWD will be turned off if inductor current is below about 100mA. In actualM P S C O N F I D E N T I A L M O U S E R E L E C T R O N I C S I N T E R N A L U S E O N L Y D O N O T D I S T R I B U T Ewaveforms the current may be much lower than this value when SWD is turned off because of internal delay.SCP/OCP vs. two current limitsThere are two current limits in MP2155. The primary one is for steady PWM opera tion and it’s typically from 2A to 3A, depending on Vin; The secondary one is for limiting inrush current at startu p, it’s typically 1.6A to 1.9A, depending on Vin, too. When load is over heavy, the primary limit would protect MP2155 from being over thermal. Therefore Vout would drop due to OCP. If Vout drops below 0.6 times normal output, a hiccup period is initiated to protect MP2155. this is the SCP. In hiccup period, SWA and SWC are turned off while SWB and SWD are turned on. After the hiccup period ends, a soft re-startup begins. Because Vout is below 1V (due to over load or output short), the secondary current takes charge of this process. After Vo rises above 1V, primary current limit get in charge of. Now if load is still over heavy (or output short still exists) such that after SS ends Vout is still below 0.6*V OUT_NORMAL and current hits one of the limits, another hiccup period begins. However if the load recovers to normal value during re-startup so that current doesn’t hit its limit, or, Vout already rises above 0.6*V OUT_NORMAL , the re-startup succeeds, and MP2155 enter normal operation.As to the input/EN startup, the cases are same as the SCP recovery process.EnableThe MP2155 has a dedicated enable control pin (EN). The device operates when it is set high. If it is set low the device stops switching, all the internal blocks are turned off. Tie EN to Vin through a resistor for automatic start up. Due to EN bias or leakage current, the value of this resistor should be set to provide EN pin with a current above 10uA. Any signal to drive this pin should be limited to 100uA if the maximum voltage of this signal is above 6.5V.Internal Soft-start When EN pin is pulled high, and at the same time the voltage on Vcc pin is above its UVLO rising threshold MP2155 will start up with Soft-start function to eliminate output overshoot. Soft-start also functions during SCP recovery.Under-Voltage Lockout The under voltage lockout (UVLO) is implement to protect the device from improper operating at insufficient supply voltage. When the supply voltage at VCC is below the UVLO threshold the device is in shutdown mode. The UVLO rising threshold is about 1.8V with 200mV hysteresis. Over-Temperature ProtectionAn internal temperature sensor continuously monitors the IC junction temperature. If the IC temperature exceeds 160ºC typically the device stops operating. As soon as the temperature falls below 140 ºC typically normal operation is restored.M P S C O N F I D E N T I A L M O U S E R E L E C T R O N I C S I N T E R N A L U S E O N L Y D O N O T D I S T R I B U T EAPPLICATION INFORMATIONSetting the Output VoltageTo use MP2155 correctly, A resistor divider must be connected between Vout and GND, and the middle point of the divider connected to FB pin as shown in Typically Application on page 1. 2R )1V V(1R FBOUT ⨯-= (1)High R2 resistance (eg. 100k Ω) can reduce the power consumption, while lower than 1M Ω resistance is recommended for R1 for good output accuracy.Inductor SelectionThe inductor is the key passive component for switching converters. With a buck-boost device, the inductor selection affects the boundary conditions in which the converter works, as buck at the maximum input voltage and as a boost at the minimum input voltage.Two critical inductance values are then obtained according to the following formulas.

As a rule of thumb, the peak-to-peak ripple can be set at 10%-20% of the output current.The minimum inductor value for the application isthe higher one between Equation 2 and Equation 3. In addition to the inductance value the maximum current the inductor can handle must be calculated in order to avoid saturation.LF V 2)V V (V I I REQ )M AX (IN OUT )M AX (IN OUT OUT BUCK PEAK ⨯⨯⨯-⨯+η=- (4) LF V )V V (V V I V I REQ OUT )M IN (IN OUT )M IN (IN )M IN (IN OUT OUT BOOST PEAK ⨯⨯-⨯+⨯η⨯=-(5) Where η is the estimated efficiency of MP2155.The maximum of the two values above must be considered when selecting the inductor.Input and Output Capacitor SelectionIt is recommended to use ceramic capacitors with low ESR as input and output capacitors in order to filter any disturbance present in the input line and to obtain stable operation.Minimum values of 10uF for both capacitors are needed to achieve good behavior of the device. The input capacitor must be placed as close as possible to the device.Other ConsiderationMP2155 employs the classic hiccup mode for SCP. This method has an inherited drawback: if the output short is released at a time closed to SS end, then Vo would has overshoot. To attenuate Vo overshoot at SCP recovery, a forward RC series can be connected in parallel with high side resistor of FB divider, as R3 and C5 in Figure 5 shows. The RC acts as a soft startup when Vo short is released at the time of internal SS’s end.PCB Layout Guide1. Input and output capacitors should be close to MP2155’s Vin, Vout and PGND pins.2. The wire connecting input capacitor to Vcc pin should be as short as possible. For better performance in noisy environment, an additional capacitor very close to Vcc pin can be used to bypass noise for Vcc.FT I A M T N I C I N U S E O Y D O D I S T R I B U 3. FB resistor divider should be very close to FB pin, and keep FB trace far away from noise.Figure 3 shows an example of PCB layout for which the reference schematic is shown on Figure 4.Top LayerBottom LayerFigure 3—PCB LayoutFigure 4—Reference Circuit for PCB GuideDesign ExampleBelow is a design example following the application guidelines for the specifications:The detailed application schematic is shown in Figure 5 and its performance can be found in TPC section.F I M C I N E D O I B TYPICAL APPLICATION CIRCUITS3.3uHL1 3.3uHFigure 5—3.3V Output Application Circuit 3.3uHGNDFigure 6—5V Output Application CircuitO EM E L T R I N U O D O D I S T U T NOTICE: The information in this document is subject to change without notice.

调压器选型计算说明书

调压器选型计算说明书说明：气态方程全名为理想气体状态方程，一般指克拉珀龙方程：pV=nRT 。

其中p 为压强，V 为体积，n 为物质的量，R 为普适气体常量，T 为绝对温度（T 的单位为开尔文(字母为K)，数值为摄氏温度加273.15,如0℃即为273.15K ）。

当p ，V ，n ，T 的单位分别采用Pa(帕斯卡)，m3(立方米)，mol ，K 时，R 的数值为8.31。

该方程严格意义上来说只适用于理想气体，但近似可用于非极端情况（低温或高压）的真实气体（包括常温常压）。

另外指的是克拉珀龙方程来源的三个实验定律：玻-马定律、盖·吕萨克定律和查理定律，以及直接结论pV/T=恒量。

波义耳-马略特定律：在等温过程中，一定质量的气体的压强跟其体积成反比。

即在温度不变时任一状态下压强与体积的乘积是一常数。

即p1V1=p2V2。

盖·吕萨克定律：一定质量的气体，在压强不变的条件下，温度每升高（或降低）1℃，它的体积的增加（或减少）量等于0℃时体积的1/273。

查理定律指出，一定质量的气体，当其体积一定时，它的压强与热力学温度成正比。

即P1/P2＝T1/T2 或pt ＝P′0（1＋t/273）式中P′0为0℃时气体的压强，t 为摄氏温度。

综合以上三个定律可得pV/T=恒量，经实验可得该恒量与气体的物质的量成正比，得到克拉珀龙方程一、调压器出口法兰处的速度调压器出口法兰处的速度，即等于调压器后端管道流速，明确大小见管道平均速度的计算结果。

可控硅调压器工作原理

可控硅调压器工作原理可控硅调压器是一种常用的电子元件，用于控制交流电的电压。

它的工作原理是基于可控硅的导通特性和控制电路的设计。

在本文中，我将详细介绍可控硅调压器的工作原理及其应用。

一、可控硅的特性可控硅是一种具有单向导通特性的半导体器件。

它由四层材料组成，分别是P型半导体、N型半导体、P型半导体和N型半导体。

当可控硅的控制电极施加正向偏置电压时，只有当阳极施加正向电压大于或等于可控硅的阈值电压时，可控硅才会导通。

一旦可控硅导通，它将保持导通状态，直到阳极电流降至零。

二、可控硅调压器的工作原理可控硅调压器的工作原理是通过控制可控硅的导通角来调节交流电的电压。

通常，可控硅调压器采用单相半波或全波整流电路，如单相半波可控硅调压器和单相全波可控硅调压器。

1. 单相半波可控硅调压器单相半波可控硅调压器由一个可控硅和一个负载组成。

当交流电源施加在可控硅的阳极和负极上时，通过控制可控硅的导通角，可以控制负载上的电压。

当可控硅导通时，负载上的电压接近交流电源的峰值；当可控硅截止时，负载上的电压接近零。

通过改变可控硅的导通角，可以调节负载上的电压。

2. 单相全波可控硅调压器单相全波可控硅调压器由两个可控硅和一个负载组成。

当交流电源施加在可控硅的阳极和负极上时，通过控制两个可控硅的导通角，可以控制负载上的电压。

当一个可控硅导通时，负载上的电压接近交流电源的峰值；当两个可控硅都截止时，负载上的电压接近零。

通过改变两个可控硅的导通角，可以调节负载上的电压。

三、可控硅调压器的应用可控硅调压器广泛应用于各种需要调节电压的场合，例如家用电器、工业设备和电力系统等。

它具有以下优点：1. 调压范围广：可控硅调压器可以调节交流电的电压范围从零到最大值，满足不同负载的需求。

2. 调压精度高：可控硅调压器可以通过控制可控硅的导通角来实现精确的电压调节，保证负载的稳定工作。

3. 响应速度快：可控硅调压器的响应速度很快，可以快速调节电压，适应负载的变化。
