Product Description

The TPS40057PWPG4 is a synchronous step-down Buck Controller 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. It 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. 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.
Input voltage feed-forward compensation
Programmable fixed-frequency up to 1MHz
Internal gate-drive outputs for high-side and synchronous N-channel MOSFETs
Thermal shutdown
Externally synchronizable
Programmable high-side sense short-circuit protection
Programmable closed-loop soft-start
<1% Internal 0.7V Reference
Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
