Description

The TPS4005x is a family of high-voltage, wide

input (8 V to 40 V), synchronous, step-down

controllers. 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 uses voltage feedforward control

techniques to provide good line regulation over the

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

to input line transients. Near-constant modulator

gain with input variation eases loop compensation.

The externally programmable current limit provides

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

operation using an internal fault counter for longer

duration overloads.

The new products, LM5145 and LM5146, offer

reduced BOM cost, higher efficiency, and reduced

solution size among many other features. Start a

WEBENCH® design with LM5145 and LM5146
