Product Summary

The TPS40200D is a flexible non-synchronous controller with a built in 200-mA driver for P-channel FETs. The circuit operates with inputs up to 52 volts with a power-saving feature that turns off driver current once the external FET has been fully turned on. This feature extends the flexibility of the device, allowing it to operate with an input voltage up to 52volts without dissipating excessive power. The applications of the TPS40200D include Industrial Control, Distributed Power Systems, DSL/Cable Modems, Scanners, Telecom.
