DESCRIPTION

The TPS4005x is a family of high-voltage, wide input

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

The TPS4005x family offers design flexibility with a

variety of user programmable functions, including

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

high-side current limit, and loop compensation.

The TPS4005x are also synchronizable to an external

supply. They incorporate 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 TPS4005x 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 hiccup mode

operation utilizing an internal fault counter for longer

duration overloads.
