Design files

Overview

The PMP40025 is a universal AC input, 48W output flyback converter based on primary side regulation(PSR) which eliminates optocouplers and secondary side feedback components reducing BOM cost. The design features a single 48V/1A output with average efficiency greater than 89% and 75mW no load power (compliant with DOE 6 &CoC V5 Tier 2 standard). The design aslo demostrates  excellent +/-3% transient response from no load to full load due to a wake up feature provided by UCC24650.

Features
  • <75mW low standby power @230Vac no load
  • +/-3% transient response from no load to full load
  • High efficiency at 10% load and four points average
  • Pass EN55022B CE test
  • Single-side PCB board for low cost
