PMP20042 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, 9V, 15V or 20V at 5A using jumpers or open drain control switches. Additional pulse-by-pulse current limiting is inherent in the current-mode controller. The board includes enable, synchronization and power good functions.

  • 3.8V to 20V in, output 5V, 9V, 15V, 20V @ 5A
  • LM5175 buck-boost controller to achieve over 90% efficiency over entire operating conditions
  • Compact size, slim form factor
  • Solution size: 57.4mm x 45.7mm
  • 98% peak efficiency
