TPS40055PWP

The TPS4005x is a family of high-voltage, wideinput (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.
