Key Document


PMP10698 is a synchronous 4-switch buck-boost converter which utilizes the LM5175 controller for USB type C applications. The output voltage can be selected for 5V, 12V or 20V at 5A using jumpers or open drain control switches. The LM5175 average current loop sets a maximum output current of 6.25A.

  • Three selectable output configurations
  • High power density
  • Cycle-by-Cycle current limit
  • Sync to external clock
  • Input and output current limit option
  • Synchronous for maximum efficiency
