USB Type-C PD DFP 5/12/20V3A Output with 2~3 Cell Battery Input Power Bank Reference Design


Design files


PMP40001 is a full featured USB type-C PD DFP reference design. The pure analog configuration for the USB type-C source controller--TPS25740 makes the PD negotiation easy. It supports 3 sets of output voltage options including 5V/12V/20V.  The max output current is 3A which provides a maximal 60W output power @20Vo. This design's total efficiency can achieve 96% at full load by adopting the high performance buck-boost controller--LM5175, which also means a good thermal performance. The valid input voltage range is from 6V to 13.5V which is compatible with the 2S and 3S lithium battery pack.

  • High dscharging power up to 20V/3A
  • Fully support USB type-C PD profile 4
  • Compatibility with 2S,3S cell input
  • High efficiency up to 96%@ full load
  • Small size with low component count
  • Pure analog configuration for USB type-C PD negotiation
