IR1176 - SYNCHRONOUS RECTIFIER DRIVER

Description

The IR1176 is a high speed CMOS controller designed to drive N-channel power MOSFETs used as synchronous rectifiers in high current, high frequency forward converters with output voltages equal or below 5VDC.

Features

  • Provides constant and proper gate drive to power Product Summary Vdd IO+/- (peak) Fmax Max lead time 5Vdc 4A/4A 2MHz 500nsec.
  • MOSFETs regardless of transformer output Minimizes loss due to power MOSFET body drain diode conduction Stand alone operation - no ties to primary side Schmitt trigger input with double pulse suppression allows operation in noisy environments High peak current drive capability - 4A High speed operation.
