... VIN pin. When a voltage is applied at the VIN pin, the HV9910B maintains a constant 7.5V at the VDD pin. This voltage is used to power the IC Supertex inc. and any external resistor dividers needed to control the IC. The VDD pin must be bypassed by a low ESR capacitor to provide a low impedance path for the high frequency current of the output GATE driver ...
