Package
Description
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 con-
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 opera-
tion. The output features two HEXFETs in a half-bridge con-
figuration with an internally set deadtime designed for mini-
mum cross-conduction in the half-bridge. Propagation delays
7 Pin Lead SIP
for the high and low side power MOSFETs
are matched to simplify use in 50% duty
cycle applications. The device can oper-
ate up to the V
IN
(max) rating.
