The default delivery mode of our store provides three kinds of modules with delivery capacity of ±5V,±12V, ±15V for customers to choose.
When using +15 source, the voltage difference between supply voltage and negative voltage should not exceed the safe voltage of the chip as far as possible.
If other outputs are needed, the customers need to adjust themselves. The output range of this module should be between ±3V~±15V
The formula for user self-configuring output power is R2=R1*1.221/(VOUT-1.221(positive voltage)
For example, when the + 5V output is needed and R1 is 10 KΩ, R2 should be 3.24kΩ R4 = R3*1.221/(VOUT-1.221) negative pressure
For example, when the output of - 5V is needed and R3 is 10KΩ, R4 should be matched with 3.24KΩ.
This module is a step-down module. The input signal needs to be more than 1V.
The input voltage should be greater than 6V if ±5V output is required. Similarly, if the output voltage is ±12V, the input voltage should be greater than 13V.
Wheel ±15V, input voltage should be greater than 16V. Module input H current: positive voltage @3A(Max) negative @2A(Max)
Name: TPS5430 Positive and Negative Power Classic Label Board
Dimension: 47mm * 43mm
Available voltage range: 5.5V-32V
TPS5430 has good characteristics, its main parameters are as follows: high current output: 3A (peak 4A); wide voltage input range: 5.5-36V; high conversion rate of the best state can reach 95%.
Wide Voltage Output Range: Fixed 500 kHz conversion rate, over-current protection and hot-break function, switch-enabled foot, shutdown state only 17 uA static current internal soft start, compared with other similar DC switching power supply conversion chip, TPS5430D high conversion rate is more worthy of attention.
The TPS5430 module sold by our store is a positive and negative power output, which facilitates the buyer's project power design, although the official PDF gives a wide voltage range to 36V peak current up to 4A. However, we hope that the buyer will not use this module when the voltage does not exceed 30V, the current control is less than 2.5A.
In addition, the actual measurement results of this baby's ripple in our shop are that the positive voltage is about 24 mV and the negative voltage is more than 40 mV. These parameters are very good for switching power supply.
In addition, according to the experience of shopkeepers using TPS5430, the actual conversion efficiency is not as high as 95% officially given, and the actual measured efficiency is about 88%. The negative pressure conversion rate is lower than that of the positive pressure.
Particular attention: The detailed description of modules in our shop is mainly for positive and negative 5V output models. Especially when using high power 10W (output 5V/2A, output 15V/0.67A), buyers are requested to add heat dissipation silicone fins and other heat dissipation chips. With better heat dissipation conditions, it is better to work for a long time within 30W (output 15V, 2A) to avoid damage to the chip by rabbits.
This TPS5430 positive and negative power supply is a classical MN watchboard, which can be more easily used in the secondary development of other projects.
Our store provides 3D package for this module.
Using Large Capacitor ESR Capacitor Filtering
High power inductor with 4A temperature rise is selected to reduce fever.
Positive power supply can carry 3A current and negative power supply can carry 2A current.
PCB reasonable layout, ripple in terms of switching power supply is low
