WIDE INPUT SYNCHRONOUS BUCK CONTROLLER

The TPS40054 TPS40055 TPS40057 is a family of High-Voltage wide input (8 V to 40 V), synchronous, Step-down converters. The TPS40054 TPS40055 TPS40057 family 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. The TPS40054 TPS40055 TPS40057 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.
