Compact 27W USB Type C Power Delivery Reference Design


Design files


The PMP20807 reference design is a USB Type C power delivery solution configurable for 5V or 9V output. This compact reference design has a total solution size of 44mm x 18mm x 7.8mm. The low quiescent current capability of LMS3635A and TPS25740A  minimizes the amount of necessary input power; the design consumes less than 1mW when in standby mode. PMP20807 features >93% efficiency for 5V configuration and >95% efficiency for 9V configuration. 

  • Small solution size:  44mm x 18mm x 7.8mm
  • >93% efficiency for 5V output, >95% efficiency for 9V output
  • <1mW of input power when in standby mode
  • Overcurrent protection
