The TPS4007x is a mid voltage, wide input (4.5 V to 28 V), synchronous, step-down converter. The TPS4007x offers design flexibility with a variety of user programmable functions, including; soft-start, UVLO, operating frequency, voltage feed-forward and high-side FET sensed short circuit protection. The TPS4007x incorporates MOSFET gate drivers for external N-channel high-side and synchronous rectifier (SR) MOSFETs. Gate drive logic incorporates 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 TPS40071 allows the supply output to sink current at all times. The TPS40070 implements a source-only power supply.
