IR2156PBF 照明镇流器驱动器, 半桥, 16.5V, 14针 PDIP封装
Description
The IR2156 incorporates a high voltage half-bridge gate driver with a programmable oscillator and state
diagram to form a complete ballast control IC. The IR2156 features include programmable preheat and
run frequencies, programmable preheat time, programmable dead-time, and programmable over-current protection. Comprehensive protection features such as protection from failure of a lamp to strike,filament fail ures, as well as an automatic restart function, have been included in the design. The IR2156 is available in both 14 lead PDIP and 14 lead SOIC packages.
