IR2151 — Self-Oscillating Half-Bridge Gate Driver IC
The IR2151 (DIP-8) is a self-oscillating half-bridge gate driver IC from Infineon (formerly International Rectifier). It integrates an internal oscillator, making it ideal for resonant converter topologies such as electronic ballasts, LLC converters, and induction heating circuits — without requiring an external PWM controller. A popular choice for DIY and industrial power electronics in Pakistan.
