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. 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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
