Product Overview

The TPS40055PWPG4 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
