10V to 32Vin 25Vout at 1A Factory Automation I/O Module Reference Design

1 января 2018

PMP20430 is a 4-switch buck-boost controller utilizing the LM5175 for industrial applications. This design has a minimum operating input voltage of 10V and a maximum input voltage of 32V, supports 25Vout @ 1A. Switching frequency is set to 600kHz, during buck-boost mode, switching frequency drops in half, the buck and boost switches at 300kHz alternately with respected max and min duty cycle.
