MPQ4326B Synchronous Step-Down Converters

Monolithic Power Systems (MPS) MPQ4326B Synchronous Step-Down Converters are configurable‑frequency step‑down regulators supporting operation from 200kHz to 2.5MHz. The MPS MPQ4326B integrates high‑side and low‑side MOSFETs to deliver 3A to 7A of efficient output current using peak‑current‑mode control for fast response and stable regulation. These converters are offered in a compact 4mm × 4mm QFN‑14 package and meet AEC‑Q100 Grade 1 automotive qualification.
