IR2156,Ballast Control IC,DIP

The IR2156 DIP Ballast Control IC from IRF is an advanced solution for fluorescent lamp ballast designs, incorporating a high-voltage half-bridge gate driver and programmable oscillator in one compact IC. This IC simplifies ballast control with features like programmable preheat frequency, preheat time, dead time, and over-current threshold, enabling precise control over lamp operation.

Engineered for efficiency and reliability, the IR2156 features a micropower startup function consuming only 150uA and robust protections, including under-voltage lockout, ESD protection, and a shutdown pin with hysteresis. Its high voltage tolerance supports a floating supply voltage of up to 625V, ensuring reliable operation in demanding applications.

The IR2156 comes in a 14-lead PDIP package, providing an easy-to-use design for compact ballast systems. With programmable features and comprehensive protections, the IR2156 is an ideal choice for high-performance fluorescent lamp ballast applications.
