USB-C DRP Power Bank With Fast Charger Input Reference Design


Design files


PMP4496 is a power bank reference design with a single USB type C dual role port (DRP). It can perform as a SINK or SOURCE. Role is automatically determined according to the external device attached. Fast charger input is also supported to save more charging time.

  • True DRP Type C Port
  • Fast Charger input supported
  • Automatic Role Detection
  • High Discharging Current
  • High Integration and Low BOM
  • Small Dimensions: 47.8mmx18.2mm
