The TPS4005x is a family of high-voltage, wide input, synchronous, step-down converters suitable for automotive applications. It 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 TPS40050-Q1 is a wide‑input (8 V to 40 V) synchronous buck controller designed for automotive and industrial power‑module applications. It offers programmable functions such as soft‑start, UVLO, feed‑forward voltage, high‑side current limit, and an externally synchronizable clock.
The datasheet includes detailed electrical characteristics, absolute‑maximum ratings, terminal descriptions, and application notes such as recommended switching‑frequency programming and external component recommendations for the SW node.
