Overview

This 5V / 3A adapter solution is fully tested and passes EMI and EMC (CE,RE) safety requirements. It implements a high efficiency primary side controller UCC28713 and synchronous rectifier UCC24610 pair. The efficiency of the design complies with Energy Star 6 and is designed to fit into small form factor housing. The design measures 44mmX35mmX15mm and has been thermally characterized. No load efficiency is <30mW over the entire operating range. Additionally the adapter solution features a 0.3V cable voltage drop compensation which makes it suitable for smartphone, tablet or dual USB port applications.

Features
  • Fully tested to comply with EMC(CE,RE) and safty requirement
  • <30mW no load power over input range
  • Valley control PSR controller +S.R controller for high efficiency (avg. 85% @230Vac)
  • Good thermal performance with low component count and shell temperature
  • Small form factor: 44mmx35mmx15mm
  • High Precision CC and CV control with 0.3V cable voltage drop compensation
