It is suitable for single/two cell battery input to drive LED light bars which contains six strings in parallel and up to 10 WLEDs per string. The internal current sinks support a maximum of ±2% current mismatching for excellent brightness uniformity in each string of LEDs. To provide enough headroom for current sink operation, the Boost controller monitors the minimum voltage of the feedback pins and regulates an optimized output voltage for power efficiency.The RT8555 has a wide input voltage operating range from 2.7V to 24V and contains I2C interface for controlling the dimming mode, operating frequency and the LED current. The internal 100mΩ, 36V power switch with current-mode control provides over-current protection. The switching frequency of the RT8555 is adjustable from 300kHz to 2MHz, which allows flexibility between efficiency and component size.The RT8555 is available in the WL-CSP-20B 1.65 x 2.05 (BSC), with pitch 0.4mm package.Product Feature●Wide Operating Input Voltage : 2.7V to 24V●High Output Voltage : Up to 36V●Programmable Channel Current : 10mA to 35mA●Channel Current Regulation with Accuracy ±3% and Matching ±2%●Dimming Controls④Direct PWM Dimming up to 20kHz and Minimum On-Time to 400ns④PWM to Analog Dimming up to 20kHz with 8-bit2C Programs LED Current, Switching Frequency, Dimming Mode●I●Switching Frequency : 300kHz to 2MHz●Current Limit, Over-Temperature Protection and Over-Voltage Protection●Input Under-Voltage Lockout●RoHS Compliant and Halogen FreeKey Performance Summary TableBench Test Setup ConditionsHeaders Description and PlacementPlease carefully inspect the EVB IC and external components, comparing them to the following Bill of Materials, to ensure that all components are installed and undamaged.

deliver 1.4W into 8Ω(MAX4364) or 1W into 8Ω(MAX4365) while operating from a single 5V supply.These devices consist of two high-output-current op amps configured as a bridge-tied load (BTL) amplifier (see Typical Application Circuit/Functional Diagram ).The gain of the device is set by the closed-loop gain of the input op amp. The output of the first amplifier serves as the input to the second amplifier, which is configured as an inverting unity-gain follower in both devices. This results in two outputs, identical in magni-tude, but 180°out of phase.BIASThe MAX4364/MAX4365 feature an internally generated common-mode bias voltage of V CC /2 referenced to G ND. BIAS provides both click-and-pop suppression and the DC bias level for the audio signal. BIAS is inter-nally connected to the noninverting input of one amplifi-er, and should be connected to the noninverting input of the other amplifier for proper signal biasing (see Typical Application Circuit/Functional Diagram ).Choose the value of the bypass capacitor as described in the BIAS Capacitor section.ShutdownThe MAX4364/MAX4365 feature a 10nA, low-power shutdown mode that reduces quiescent current con-sumption. Pulling SHDN high disables the device’s bias circuitry, the amplifier outputs go high impedance, and BIAS is driven to GND. Connect SHDN to GND for nor-mal operation.Current LimitThe MAX4364/MAX4365 feature a current limit that pro-tects the device during output short circuit and over-load conditions. When both amplifier outputs are shorted to either V CC or GND, the short-circuit protec-tion is enabled and the amplifier enters a pulsing mode,reducing the average output current to a safe level. The amplifier remains in this mode until the overload or short-circuit condition is removed.Applications InformationBridge-Tied LoadThe MAX4364/MAX4365 are designed to drive a load differentially in a BTL configuration. The BTL configura-tion (Figure 1) offers advantages over the single-ended configuration, where one side of the load is connected to ground. Driving the load differentially doubles the output voltage compared to a single-ended amplifier under similar conditions. Thus, the differential gain ofthe device is twice the closed-loop gain of the input amplifier. The effective gain is given by:Substituting 2 V OUT(P-P)into the following equations yields four times the output power due to doubling of the output voltage.Since the differential outputs are biased at midsupply,there is no net DC voltage across the load. This elimi-nates the need for DC-blocking capacitors required for single-ended amplifiers. These capacitors can be large, expensive, consume board space, and degrade low-frequency performance.Power DissipationUnder normal operating conditions, the MAX4364/MAX4365 can dissipate a significant amount of power.The maximum power dissipation for each package is given in the Absolute Maximum Ratings section under Continuous Power Dissipation or can be calculated by the following equation:where T J(MAX)is +150°C, T A is the ambient temperature and θJA is the reciprocal of the derating factor in °C/W as specified in the Package Thermal Characteristics section. For example, θJA of the µMAX package is 206.3°C/W.A RR VD FIN=×2MAX4364/MAX43651.4W and 1W, Ultra-Small, Audio PowerAmplifiers with Shutdown_______________________________________________________________________________________9Figure 1. Bridge-Tied Load ConfigurationM A X 4364/M A X 4365The increase in power delivered by the BTL configura-tion directly results in an increase in internal power dis-sipation over the single-ended configuration. The maximum power dissipation for a given V CC and load is given by the following equation:If the power dissipation for a given application exceeds the maximum allowed for a given package, reduce V CC , increase load impedance, decrease the ambient temperature or add heat sinking to the device. Large output, supply, and ground PC board traces improve the maximum power dissipation in the package.Thermal-overload protection limits total power dissipa-tion in the MAX4364/MAX4365. When the junction tem-perature exceeds +160°C, the thermal protection circuitry disables the amplifier output stage. The ampli-fiers are enabled once the junction temperature cools by 15°C. This results in a pulsing output under continu-ous thermal overload conditions as the device heats and cools.The MAX4365 TDFN package features an exposed thermal pad on its underside. This pad lowers the ther-mal resistance of the package by providing a direct heat conduction path from the die to the PC board.Connect the exposed thermal pad to circuit ground by using a large pad, ground plane, or multiple vias to the ground plane.EfficiencyThe efficiency of the MAX4364/MAX4365 is calculated by taking the ratio of the power delivered to the load to the power consumed from the power supply. Output power is calculated by the following equations:where V PEAK is half the peak-to-peak output voltage. In BTL amplifiers, the supply current waveform is a full-wave rectified sinusoid with the magnitude proportional to the peak output voltage and load. Calculate the sup-ply current and power drawn from the power supply by the following:The efficiency of the MAX4364/MAX4365 is:The device efficiency values in Table 1 are calculated based on the previous equation and do include the effects of quiescent current. Note that efficiency is low at low output-power levels, but remains relatively con-stant at normal operating, output-power levels.Component SelectionGain-Setting ResistorsExternal feedback components set the gain of both devices. Resistors R F and R IN (see Typical Application Circuit/Functional Diagram ) set the gain of the amplifier as follows:Optimum output offset is achieved when R F = 20k Ω.Vary the gain by changing the value of R IN . When using the MAX4364/MAX4365 in a high-gain configuration (greater than 8V/V), a feedback capacitor may be required to maintain stability (see Figure 2). C F and R F limit the bandwidth of the device, preventing high-fre-quency oscillations. Ensure that the pole created by C F and R F is not within the frequency band of interest.Input FilterThe input capacitor (C IN ), in conjunction with R IN forms a highpass filter that removes the DC bias from an incoming signal. The AC-coupling capacitor allows the amplifier to bias the signal to an optimum DC level.Assuming zero source impedance, the -3dB point of the highpass filter is given by:Choose R IN according to the G ain-Setting Resistors section. Choose C IN such that f -3dB is well below the lowest frequency of interest. Setting f -3dB too high affects the low-frequency response of the amplifier. Use capacitors whose dielectrics have low-voltage coeffi-1.4W and 1W, Ultra-Small, Audio Power Amplifiers with Shutdown 10______________________________________________________________________________________cients, such as tantalum or aluminum electrolytic.Capacitors with high-voltage coefficients, such as ceramics, may result in an increase distortion at low frequencies.Other considerations when designing the input filter include the constraints of the overall system, the actual frequency band of interest and click-and-pop suppres-sion. Although high-fidelity audio calls for a flat gain response between 20Hz and 20kHz, portable voice-reproduction devices such as cellular phones and two-way radios need only concentrate on the frequency range of the spoken human voice (typically 300Hz to3.5kHz). In addition, speakers used in portable devices typically have a poor response below 150Hz. Taking these two factors into consideration, the input filter may not need to be designed for a 20Hz to 20kHz response,saving both board space and cost due to the use of smaller capacitors.BIAS CapacitorThe BIAS bypass capacitor, C BIAS , improves PSRR and THD+N by reducing power-supply noise at the common-mode bias node, and serves as the primary click-and-pop suppression mechanism. C BIAS is fed from an internal 25k Ωsource, and controls the rate at which the common-mode bias voltage rises at startup and falls during shutdown. For optimum click-and-pop suppres-sion, ensure that the input capacitor (C IN ) is fully charged (ten time constants) before C BIAS . The value of C BIAS for best click-and-pop suppression is given by:In addition, a larger C BIAS value yields higher PSRR.MAX4364/MAX4365Amplifiers with Shutdown______________________________________________________________________________________11Figure 2. High-Gain ConfigurationM A X 4364/M A X 4365Clickless/Popless OperationProper selection of AC-coupling capacitors (C IN ) and C BIAS achieves clickless/popless shutdown and startup.The value of C BIAS determines the rate at which the midrail bias voltage rises on startup and falls when enter-ing shutdown. The size of the input capacitor also affects clickless/popless operation. On startup, C IN is charged to its quiescent DC voltage through the feedback resistor (R F ) from the output. This current creates a voltage tran-sient at the amplifier’s output, which can result in an audible pop. Minimizing the size of C IN reduces this effect, optimizing click-and-pop suppression.Supply BypassingProper supply bypassing ensures low-noise, low-distor-tion performance. Place a 0.1µF ceramic capacitor in parallel with a 10µF ceramic capacitor from V CC to G ND. Locate the bypass capacitors as close to the device as possible.Adding Volume ControlThe addition of a digital potentiometer provides simple volume control.Figure 3 shows the MAX4364/MAX4365with the MAX5407 log taper digital potentiometer used as an input attenuator. Connect the high terminal of the MAX5407 to the audio input, the low terminal to ground and the wiper to C IN . Setting the wiper to the top posi-tion passes the audio signal unattenuated. Setting the wiper to the lowest position fully attenuates the input.Layout ConsiderationsG ood layout improves performance by decreasing the amount of stray capacitance and noise at the amplifier’s inputs and outputs. Decrease stray capacitance by min-imizing PC board trace lengths, using surface-mount components and placing external components as close to the device as possible. Also refer to the Power Dissipation section for heatsinking considerations.Amplifiers with Shutdown 12______________________________________________________________________________________Figure 3.

After reset, the OS generates adeterminate sequence on the Q8 pin. If this sequence is copied to the Q7, the OS jumps to the PGM bootloader. (The PGMmode is indicated by short red LED flashing every 2 s.)This must be taken into account to avoid collisions with application circuitry connected to these pins.The Q7 pin must not be interconnected to Q8 or left unconnected or without a defined level on its input. Thislevel must be arranged by application hardware. If the application circuitry ensures no such level, a pull-down resistor on Q7 pin must be used otherwise a cross-talk between Q8 and Q7 may cause anunintentional switching to PGM.Note 3: This pin is affected by IQRF OS (and possibly DPA) LED functions and system LED indication.There are no on-board protection series resistors on I/O pins. It is recommended to use 200 Ω series resistors on each pin. See the application note AN015 - IQRF HW design for TR-7xD transceivers.Recommended circuit for developmentFor development, it is recommended to implement the following arrangement:•Decoupling capacitor on V CC to filter the supply voltage. The type and the value should be selected with respect to general rules observed in electronic design, according to given application hardware and power source.•Serial protective resistors on each I/O pin used.•Both system LEDs (LEDR and LEDG) for IQRF OS and DPA status indication and for possible user indication. When the Q10 and Q11 pins are used as user I/Os, it must be taken into account that these pins can be affected by IQRF OS or DPA.•Pin Q12 configured as an input with the internal pull-up resistor and equipped with a pushbutton connected to the ground.Then pressing the button can generate an interrupt on pin change, wake-up the transceiver from sleep, terminate RFPGM mode, initiate bonding etc.•Pull-down resistor on pin Q7 recommended to avoid unintentional switching to PGM mode due to SDO - SDI cross-talk during TR boot.•SPI interface for wired upload of application code into the transceiver using an IQRF programmer, e.g CK-USB-04A.RF rangeRF range strongly depends on the following design aspects:•Hardware:•Construction of the devices (especially TR location within the device, PCB layout, ground planes, conductive areas and bulk objects such as metallic parts and batteries in the nearest surroundings, with respect to possible reflections and counterpoise effect). To achieve an efficient range and reliable connectivity, no parts impacting the range must be placed close to the built-in meander antenna. Even non-conductive parts including a mainboard PCB under the antenna can significantly impact the range.•Physical arrangement of devices (especially mutual orientations of antennas with respect to polarizations and radiation patterns)•Application software:•RF output power is selectable from 8 levels•To increase immunity to RF noise, incoming RF signal can be filtered according to signal strength.Refer to IQRF OS Reference guide, function checkRF and Application note AN014 RF range optimizing at TR-7xDx transceivers.Diagram 1: TR-7xDA RF output power [in dBm] vs. antenna orientation (radiation patterns).Examples of the correct and incorrect arrangement of TR-7xDA pairs:Correct Correct Incorrect Incorrect IncorrectWrong radiation angle Mismatched polarization Wrong radiation angleMismatched polarizationDiagram 2A: Effective radiated power (ERP) vs. level in the setRFpower(level) function.

FPGA可编程逻辑器件芯片AD8552ARZ-REEL7中文规格书
With an offset voltage of only 1 μV and drift of 0.005 μV/°C, the AD8551/AD8552/AD8554 are perfectly suited for applications in which error sources cannot be tolerated. Temperature, position and pressure sensors, medical equipment, and strain gage amplifiers benefit greatly from nearly zero drift over their operating temperature range. The rail-to-rail input and output swings provided by the AD8551/AD8552/AD8554 make both high-side and low-side sensing easy.
