USB Type-C PD DFP Charger 5V/12V3A Out Adapter Reference Design


Design files


The PMP4489 reference design is a dedicated USB-C PD2.0 DFP 5V/12V3A output flyback converter with secondary-side regulation UCC28740DR which provides Constant-Voltage Constant-Current feature. The design features <75mW standby power(compliant with DOE 6 &CoC V5 Tier 2 standard). Secondary voltage-second balance synchronous rectifier UCC24636 enables high efficiency with maximum SR conduction time . TPS25740 implements a fully compliant USB Power Delivery 2.0 provider and Type-C downward facing port(DFP).

  • High efficiency for good thermal
  • Compliant with CoC V5 Tier 2 2016
  • Compliant with USB Power Delivery 2.0 and Type-C
  • Eliminate the ESD protection circuit on CC1,CC2
  • Small size adapter
