Key Document


The PMP11612 is a reference design for 5V 2A adapter applications. The solution implements a high efficiency primary side controller UCC28704, it is fully test and passes conduction and Radiation EMI. This design uses diode rectifier for low cost and meets COC V5 Tier2 2016 specification with 150mOhm cable. The board measures 47mmX34mmX15mm. A low cost EE16 general transformer is used .

  • Diode rectifier QR Flyback with primary side regulation
  • High 4-point average efficiency above 80% with 150mohm cable
  • Good thermal performance with low component count
  • Fully tested and passes CE/RE
  • Size 47mm x 34mm x 15mm
