Description
The IR53H(D)420 are complete high voltage, high speed, self- oscillating half-bridge circuits. Proprietary HVIC and latch im- mune CMOS technologies, along with the HEXFET
®
power MOSFET technology, enable ruggedized single package con- 7-Lead SIP struction. The front-end features a programmable oscillator which functions similar to the CMOS 555 timer. The supply to the control circuit has a zener clamp to simplify offline operation. The output features two HEXFETs in a half-bridge configuration with an internally set deadtime designed for minimum cross-conduction in the half-bridge. Propa- gation delays for the high and low side power MOSFETs are matched to simplify use in 50% duty cycle applications. The device can operate up to the VIN (max) rating.
