Introduction

The Supertex HV312DB1 demo board contains all circuitry necessary to demonstrate the features of the HV312 hotswap controller. Intended primarily as a negative hotswap controller, the HV312 controls the negative supply path. Four sequenced power-good signals are provided, with timing controlled via 3 resistors.

Included on board is a 100*F capacitor to provide a capacitive load for testing. Additional capacitance may be connected to the VOUT terminals. Or the 100*F may be removed altogether

The board may be modified to meet custom requirements. Instructions are provided on the next page for modifications.
