Design files

Overview

Constant Voltage/Constant Current  power supply generates 5V at 2A output. The design features primary side regulation (PSR) of a power transistor (BJT). With a low component count and low cost, the design can be use in USB type power supplies for PDA's, tablets, cameras and cell phones.

Features
  • Primary Side Regulation (PSR)
  • ± 5% Voltage Regulation
  • ± 5% Current Regulation
  • Low Stand-by Power
  • Valley Switching
  • High Voltage Startup
  • Low Cost BJT control
