The TPS40075 is a mid-range input synchronous buck controller with features such as fixed-frequency voltage-mode control and predictive gate drive, which can maximize efficiency.
The TPS40075 is a mid‑voltage, wide‑input (4.5 V to 28 V) synchronous step‑down controller that offers programmable functions such as soft‑start, UVLO, feed‑forward, and short‑circuit protection. It drives external N‑channel MOSFETs with Predictive Gate Drive™ Generation II for high efficiency and includes a 20‑pin QFN package for compact thermal performance.
The document contains device ratings, electrical characteristics, terminal information, recommended operating conditions, typical characteristics, layout guidelines, and application notes. It also provides design examples and references for engineers designing power modules, networking, telecom, industrial, and server applications.
