About this product
A self-oscillating half-bridge driver IC in an 8-pin SOP package. It generates its own switching frequency, which is set by external RC components, and drives the two power MOSFETs of a half-bridge. It is commonly used in electronic ballasts, compact fluorescent lamp drivers and small switch-mode power supplies.

Frequently asked questions
How do I set the switching frequency?
The frequency is set by the external resistor and capacitor values. Use the formula and component guidance in the IR2153 datasheet.
Is it suitable for mains-powered circuits?
It is used in mains-powered ballast and SMPS designs, but high-voltage work needs proper isolation and safety precautions. Follow the datasheet closely.
