Vishay VOM1272 Optically Isolated MOSFET Driver
Vishay Semiconductors VOM1272 Optically Isolated MOSFET Driver is a stand-alone photovoltaic driver for isolated MOSFET gate-drive applications. The VOM1272 obtains the current required for its internal circuitry from the LED current on the low-voltage primary side of the isolation barrier, helping eliminate the need for one or more external power supplies. Integrated rapid turn-off circuitry reduces the need for additional external components and improves switching speed.
