Description

15 W 5 V Adapter Reference Boardwith ICE2QS03G, IR1161, IPS65R1K5CE, BSZ100N06LS3 G and BASW21-03W

Features

Quasi resonant operation till very low load

  • Active burst mode operation at light/no load for low standby input power (< 100mW)
  • Digital frequency reduction with decreasing load
  • Startup cell for VCC pre-charging with constant current
  • Built-in digital soft-start
  • Foldback correction and cycle-by-cycle peak current limitation
  • Auto restart mode for VCC Over-voltage protection, VCC Under-voltage protection and open loop/over-loadprotection
  • Latch-off mode for adjustable output over-voltage protection and short-winding protection

Typical applications

  • Adapter/Charger
  • LCD monitor, DVD R/W, DVD Combo, Blue-ray/DVD player, Set-top box,
  • Auxiliary power supply for CRT TV, LCD TV, PC, Server, Printer, TV, Home theater/Audio System, etc.
