The TPS40074 is a mid voltage, wide input (4.5-V to 28-V), synchronous, step-down controller, offering design flexibility for a variety of user programmable functions, including; soft start, UVLO, operating frequency, voltage feed-forward and high-side FET sensed short circuit protection.

The TPS40074 incorporates MOSFET gate drivers for external N-channel high side and synchronous rectifier (SR) MOSFETs. The gate drive logic incorporates second generation predictive anti-cross conduction circuitry to prevent simultaneous high side and synchronous rectifier conduction, while minimizing to eliminating current flow in the body diode of the SR FET. The TPS40074 allows for starting into pre-biased outputs by not allowing the synchronous rectifier FET to turn on until the commanded voltage during soft start is greater than the existing pre-bias voltage.
