DESCRIPTION

The TPS40055 is a family of high-voltage, wide input

(8 V to 40 V), synchronous, step-down converters.

The TPS40055 family offers design flexibility with a

variety of user programmable functions, including

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

Programmable High-Side Sense Short-Circuit

Protection

The TPS40055 are also synchronizable to an external

supply. The TPS40055 incorporates MOSFET gate

drivers for external N-channel high-side and

synchronous rectifier (SR) MOSFETs. Gate drive

logic incorporates anti-cross conduction circuitry to

prevent simultaneous high-side and synchronous

rectifier conduction.

The TPS40055 uses voltage feed-forward control

techniques to provide good line regulation over the

wide (4:1) input voltage range and fast response to

input line transients with near constant gain with input

variation which eases loop compensation. The

externally programmable current limit provides pulse-

by-pulse current limit, as well as a hiccup mode

operation utilizing an internal fault counter for longer

duration overloads.
