IR2153 – Self-Oscillating Half-Bridge Gate Driver IC

MPN:IR2153
The IR2153 IC is a high-voltage, self-oscillating half-bridge gate driver IC designed for driving N-channel MOSFETs or IGBTs. It integrates a voltage-controlled oscillator, dead-time control, and high-side/low-side gate drivers in a single package.

The device is widely used in electronic ballasts, SMPS, inverters, induction heating, and resonant converters due to its simplicity and minimal external component requirement.

Originally developed by International Rectifier (IR) (now part of Infineon Technologies), the IR2153 is often referenced in designs regardless of distributor or manufacturer branding.
