IR53HD420 - International Rectifier

IR53HD420 SELF-OSCILLATING HALF BRIDGE

The IR53H(D)420(-P2) are complete high voltage, high speed, self-oscillating half-bridge circuits. Proprietary HVIC and latch immune CMOS technologies, along with the HEXFET® power MOSFET technology, enable ruggedized single package construction. The front-end features a programmable oscillator which functions similar to the CMOS 555 timer. The supply to the.
