... C . × × Zener clamped Vcc for offline operation n Half-bridge output is out of phase with R Description The IR51HD320 is a high voltage, high speed, self- oscillating half-bridge. Proprietary HVIC and latch immune CMOS technologies, HEXFET ® power MOSFET technology, ruggedized single package construction. The front-end features a programmable oscillator which functions similar to the CMOS 555 timer ...

... CC T Ambient Temperature A Note 1: Because of the IR51HD320's application specificity toward off-line supply systems, this IC contains a zener clamp structure between the chip V 15.6V. Therefore, the IC supply voltage is normally derived by current feeding the V (typically by means of a high value resistor connected between the chip V voltage and a local decoupling capacitor from V circuit to determine the nominal supply voltage ...
