ICE2QS03 - Quasi-Resonant PWM Controller

Datasheet Summary

Description

ICE2QS03 is a quasi-resonant PWM controller optimized for off-line switch power supply applications such as LCD TV, CRT TV and notebook adapter.

The digital frequency reduction with decreasing load enables a quasi-resonant operation till very low load.

Features

  • Quasiresonant 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 Power 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 Overvoltage protection Auto restart mode for.
