Description

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.

Features
  • 10V to 32V in, output 25V @ 1A
  • Achieving efficiency of 90% across entire operation range, 96% peak efficiency
  • Compact size, slim form factor
  • Solution size:  24mm x 20mm
  • LM5175 4-switch buck-boost controller, wide Vin, high efficiency
