IR2085S - HIGH SPEED/ 100V/ SELF OSCILLATING 50% DUTY CYCLE/ HALF-BRIDGE DRIVER

Description

The IR2085S is a self oscillating half-bridge driver IC with 50% duty cycle ideally suited for 36V-75V half-bridge DC-bus converters.

This product is also suitable for push-pull converters without restriction on input voltage.

Features

  • Simple primary side control solution to enable half-bridge DC-Bus Converters for 48V distributed systems with reduced component count and board space. Integrated 50% duty cycle oscillator & half-bridge driver IC in a single SO-8 package Programmable switching frequency with up to 500kHz max per channel +/- 1A drive current capability optimized for low charge MOSFETs Adjustable dead-time 50nsec.
