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 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 - 2MHz

• Adaptable to multiple topologies
