The PX3511D is a high frequency MOSFET driver specifically designed to drive upper and lower power N-Channel MOSFETs in a synchronous rectified buck converter topology.
The PX3511D is a high‑frequency MOSFET driver designed for synchronous‑rectified buck converter topologies. It drives upper and lower N‑channel MOSFETs with a flexible gate‑drive voltage range and includes advanced adaptive zero shoot‑through protection, pre‑POR over‑voltage protection, and input high‑impedance detection.
The document details electrical specifications, recommended operating conditions, pin‑out information, layout guidelines, and thermal considerations, helping designers integrate the driver into high‑efficiency power‑management solutions for microprocessor core‑voltage regulation.
