Overview

PMP10708 is a 7.8W 4-switch buck-boost converter using the LM5175 controller IC. The design accepts an input voltage of 3.5Vin to 36Vin and provides an output of 6.5Vout capable of supplying 1.2A of current to the load. The design can operate as low as 3V during start-stop or other line transient conditions.

Features
  • Very small solution size
  • Cycle-by-Cycle current limit
  • Sync to external clock
  • Input and output current limit option
  • Synchronous for maximum efficiency
  • Reverse polarity and 3Vin transient operation
