Function Description

Input Voltage Regulator

The FP7175 can be powered directly from its VIN pin and can work from 8.5 - 100VDC at its VIN

pin. When a voltage is applied at the VIN pin, the FP7175 maintains a constant 7.5V at the VDD pin.

This voltage is used to power the IC 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.

The FP7175 can also be operated by supplying a voltage at the VDD pin greater than the

internally regulated voltage. This will turn off the internal linear regulator of the IC and the FP7175 will

operate directly off the voltage supplied at the VDD pin. Please note that this external voltage at the

VDD pin should not exceed 8.5V.
