ICE2QR0665G Datasheet Off-line Smps Quasi-resonant Pwm Controller

Manufacturer: Infineon

Overview: ICE2QR0665G Quasi-Resonant, 650V CoolSET™ in DS0-12 Package Product Highlights  Active Burst Mode to reach the lowest standby power requirement <100 mW @ no load  Quasi resonant operation  Digital frequency reduction.

General Description

The CoolSETTM-Q1 series (ICE2QRxx65G) is the first generation of quasi-resonant integrated power ICs.

It is optimized for off-line switch mode power supply applications such as LCD monitor, DVD R/W, DVD bo, Blue-ray DVD, set top box, etc.

Operating the MOSFET switch in quasi-resonant mode, lower EMI, higher efficiency and lower voltage stress on secondary diodes are expected for the SMPS.

Key Features

  • 650V avalanche rugged CoolMOSTM with built-in startup cell.
  • Quasi resonant operation till very low load.
  • Active burst mode operation for low standby input power (< 0.1W).
  • Digital frequency reduction with decreasing load for reduced switching loss.
  • Built-in digital soft-start.
  • Foldback point correction, cycle-by-cycle peak current limitation and maximum on time limitation.
  • Auto restart mode for VCC over-voltage protection, under- voltage protection, over-load p.
