TPS54360 positive and negative voltage negative voltage reversal power supply op amp power supply regulated power supply
TPS54360 positive and negative voltage negative voltage reversal power supply op amp power supply regulated power supplyKW_543602 module shipping listModule + after-sale technical support + electrostatic bag packaging + shockproof foamTips:(1) The module interface of our store is clear and the performance is stable. Please combine the data provided by our store to perform functional verification under the corresponding experimental conditions.(2) This product is a simple functional module, no schematic diagram is provided, and the basic parameters are in the detail page. Please be clear to the buyer, if you have any operation problems, please consult customer service.(3) Buyers, before using the module, please read the details page of this module to understand the power supply and use restrictions, to avoid damage to the module due to improper operation.(4) Our modules are guaranteed to provide real module parameters, functions and pictures, and all modules will be shipped after detection.Module parametersModule model: KW_543602Module type: switching power supply; step-down typeInput voltage: 7V-40V; due to the negative pressure conversion circuit, the absolute value of the input and output pressure difference of the negative voltage power supply side is less than 60V, for example: negative pressure output -15V, then the input voltage must not be higher than 45V; in order to adapt to the negative pressure The indicator, the maximum input safety voltage of the module is recommended to be less than 40VOutput voltage: four types; four specifications are available: ±5V, ±9V, ±12V, ±15VOutput current: 3.5A (positive pressure) 2.4A (negative pressure); the maximum output current is asymmetric, please pay attention to the current limit when usingConversion efficiency: positive pressure up to 91%; negative pressure better than 77%Input and output minimum pressure difference: about 2VStatic power consumption: 5mA; for reference onlyLoad adjustment rate: ±0.5%; for reference onlyVoltage regulation rate: ±1%; for reference onlySwitching frequency: 600KHzOutput ripple: better than 40mV (+5V@3.5A); better than 40mV (-5V@2.4A)Module enable: user can configure input undervoltage protectionModule protection: chip comes with overheat, overvoltage and frequency foldback protectionModule features: multiple; low noise, low ripple; with output power indicatorModule applications: multiple; industrial, automotive, and communications power systemsModule weight: 55g; with radiatorModule size: 50×50×27 length×width×height (mm)Module heating: the greater the load, the greater the heatingWorking temperature: 0-70℃ Civil gradeModule interface: 5.08 terminal; input: 5.08-2P, output: 5.08-3PModule descriptionThis module adopts TPS54360 chip, the maximum load current of positive pressure can reach 3.5A, and the theoretical conversion efficiency can reach 91%. The chip has overheating, overvoltage and frequency foldback protection. When using it for a long time under high power, please pay attention to the heat of the module (chip, inductor, diode) to avoid overheat protection of the chip. The module refers to the official design specification for layout and wiring, generous materials, small ripple, convenient and practical. Suitable for student competition use and personal project development.
Precautions for using the module(1) Since the working voltage of the EN pin of the chip is –0.3V—8.4V (the chip is enabled when it is greater than 1.2V) and the chip has an internal pull-up current source of 1.2μA, the chip can also work when the EN terminal is left floating; for compatibility Wider input range The module's enable voltage divider is not welded. If you need to modify the undervoltage protection, please configure R3, R6 and R9, R13. For example: R3=300K, R6=47K; when VIN is less than 9V, the partial voltage is less than 1.2V, the positive voltage does not work, the negative voltage is the same, and the undervoltage protection is realized; please refer to the chip manual for more details.(2) When the module is used, 100uF or larger electrolytic capacitors can be added to the input and output terminals to improve ripple.(3) There is no reverse connection protection for this module, please buyers carefully check and compare the power supply and then power on, otherwise it will damage the module.(4) The power supply heating is mainly determined by the input and output voltage difference and the load current, please choose and use the power supply module reasonably, generally need to reserve 30% of the surplus.(5) The module is a step-down module. The input voltage needs to be greater than the output of about 2V to stabilize the output.Frequently asked questionsQ: Why does the maximum output of the module not reach the nominal value when I use it?A: To achieve high output power, the input power of the module must be greater than the output power.Q: Why can't I test the nominal ripple parameters?A: First of all, you need to have a correct measurement method, which can be used to measure the ripple of Baidu power supply. Secondly, the input-output voltage difference and the load current have a certain influence on the output ripple.
