The TPS40056 is part of a family of high-voltage, wide input, synchronous, step-down converters. The TPS40056 offers design flexibility with a variety of user programmable functions, including soft-start, operating frequency, high-side current limit, and loop compensation. The TPS40056 is also synchronizable to an external supply. It incorporates 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 externally programmable short circuit protection provides pulse-by-pulse current limit, as well as hiccup mode operation utilizing an internal fault counter for longer duration overloads.
