DESCRIPTION
The TPS40052 is part of a family of high-voltage,
wide input, synchronous, step-down converters.
The TPS40052 offers design flexibility with a
variety of user programmable functions, including
soft-start, operating frequency, high-side current
limit, and loop compensation.
The TPS40052 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.
