Monolithic Power Systems
MPQ4571GQB-AEC1-Z
High-Efficiency, 1A, 60V, Synchronous Buck Converter, AEC-Q100
The MPQ4571 is a fully integrated, fixed-frequency, synchronous step-down converter capable of achieving up to 1A of continuous output current. It operates over a wide 4.5V to 60V input range and features peak current control for excellent transient response. The device integrates high-side and low-side power MOSFETs, advanced asynchronous modulation (AAM) for light-load efficiency, and low-dropout mode for automotive cold crank conditions. Protection features include over-current protection with valley current detection, hiccup short-circuit protection, and thermal shutdown.
