DESCRIPTION

The TPS40200 is a flexible nonsynchronous controller with a built-in 200-mA driver for P-channel FETs. The

circuit operates with inputs up to 52 V, 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 52 V, without dissipating excessive power. The circuit operates with voltage-mode feedback and

has feed-forward input-voltage compensation that responds instantly to input-voltage change. The integral 700-

mV reference is trimmed to 2%, providing the means to accurately control low voltages. The TPS40200 is

available in an 8-pin SOIC, and supports many of the features of more complex controllers. Clock frequency, soft

start, and overcurrent limit each are easily programmed by a single, external component. The part has

undervoltage lockout, and can be easily synchronized to other controllers or a system clock to satisfy sequencing

and/or noise-reduction requirements.
