HV100 Demo Board HV100DB1 3-Pin Hotswap Controller Introduction The Supertex HV100DB1 demo board contains all necessay circuitry to demonstrate the features of the HV100 hotswap controller. Intended primarily as a negative hotswap controller, the HV100 controls the negative supply path. Included on board is a 100µF capacitor (C3) to provide a capacitive load for testing. Additional capacitance may be connected to the VOUT terminals. Or the 100µF may be removed altogether The board may be modified to meet custom requirements. Instructions are provided on the next page for modifications.
