DESCRIPTION

The TPS40060 and TPS40061 are high-voltage, wide

input (10 V to 55 V) synchronous, step-down

converters.

This family of devices offers design flexibility with a

variety of user programmable functions, including;

soft-start, UVLO, operating frequency, voltage feed-

forward, high-side current limit, and loop

compensation. These devices are also

synchronizable to an external supply.

The TPS40060 and TPS40061 incorporate MOSFET

gate drivers for external P-channel high-side and Nchannel

synchronous rectifier (SR) MOSFETs. Gate

drive logic incorporates anti-cross conduction circuitry

to prevent simultaneous high-side and synchronous

rectifier conduction.
