Monolithic Power Systems, Inc. Dc/dc Conv, Sync Buck, 2.2Mhz, 125Deg C; Topology Monolithic Power Systems (Mps) MPM3509GQVE-AEC1-P

The MPM3509 is a synchronous step-down DC/DC converter designed for high efficiency and compactness. It operates within a wide input voltage range of 4V to 36V and delivers a continuous output current of 0.9A. The device features integrated power MOSFETs, inductors, and capacitors, requiring only four external components for operation. With a fixed switching frequency of 2.2MHz, it provides a fast load transient response and includes protection features such as over-current protection and thermal shutdown. The MPM3509 is housed in a QFN-17 package measuring 3mm x 5mm x 1.6mm, making it suitable for space-constrained applications. It is AEC-Q100 qualified, indicating its reliability for automotive applications, and is compliant with CISPR25 Class 5 for EMI performance. This converter is ideal for use in industrial controls, automotive, medical equipment, telecom applications, and distributed power systems.
