IR1175 - Synchronous Rectifier Driver

Description

The IR1175 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

  • n Provides constant and proper gate drive to power MOSFETs regardless of transformer output n Minimizes loss due to power MOSFET body drain diode conduction n Stand alone operation - no ties to primary side n Schmitt trigger input with double pulse suppression allows operation in noisy environments n High current drive capability - 2A n High speed operation - 2MHz n Adaptable to multiple topologies (such as singleended forward, double-ended forward) Product Summary Vdd IO+/Fmax Max lead time 5V.
