IR1166SPbF - SmartRectifier CONTROLLER

General Description

IR1166S is a smart secondary side driver IC designed to drive N-Channel power MOSFETs used as synchronous rectifiers in isolated Flyback converters.

The IC can control one or more paralleled N-MOSFETs to emulate the behavior of Schottky diode rectifiers.

Key Features

  • • • • • • • • • Secondary side high speed SR controller DCM, CrCM and CCM flyback topologies 200V proprietary IC technology Max 500KHz switching frequency Anti-bounce logic and UVLO protection 4A peak turn off drive current Micropower start-up & ultra low quiescent current 10.7V gate drive clamp • • • • • • • 50ns turn-off propagation delay Vcc range from 11.3V to 20V Direct sensing of MOSFET drain voltage Minimal component count Simple design Lead-free Compatible with 1W Standby, Energy Star,.
