VOM1271T

The VOM1271T is a standalone optically isolated MOSFET Driver. Unlike conventional MOSFET drivers, which require an external power supply to provide VCC and or VDD rails to the driver itself, this obtains all the required current to drive its internal circuitry from the LED current on the low voltage primary side of the isolation barrier. This saves the designer the space and cost associated with providing one or more external power supplies. This also integrates a turn-off circuit internal to the component itself, thus doing away with the need for additional components in order to increase the overall switching speed by decreasing the turn-off time.
