Description

This 5V / 1.5A adapter solution is fully tested and passes EMI and EMC (CE,RE) safety requirements. It implements a low cost primary side Bipolar controller UCC28722. The efficiency of the design is 78% with standby power less than 100mW. The design is very slim; the size is 30mmX35.3mmX8mm and has been thermally characterized.

Features
  • Fully tested to comply with EMC(CE,RE) and safety requirement
  • <100mW no load power over input range
  • Valley control PSR controller
  • Good thermal performance with few component count and low shell temperature
  • Small form factor: 30mmX35.3mmX8mm
  • Low Cost
