TPS5430 switching power supply module positive and negative regulated power supply meter board low ripple positive and negative 5V -79496
product detail
Provide the output of ± 5, ± 12V, ± 15V three options, for other output, customers need to adjust their own, The specific formula is R2 = R1 * 1.221 / (VOUT-1.221) --- Corresponding to the Silkprint on board.
For example, you need + 5V output, R1 is 10KΩ, R2 should be equipped with 3.24KΩ, R4 = R3 * 1.221 / (VOUT-1.221) (Negative voltage)
For example, you need - 5V output, R1 is 10KΩ, R4 should be equipped with 3.24KΩ.
This module is a step-down module, the input signal must be greater than the output 1V above
For output ± 5V, the input voltage should be greater than 6V
