MPQ4573 Switching Converters

Monolithic Power Systems (MPS) MPQ4573 Switching Converters are fully integrated, fixed-frequency, and synchronous step-down converters. These converters can achieve up to 2.5A of continuous output current with peak current control for a good transient response. The MPQ4573 converters are integrated with an internal High-Side (HS-FET) and Low-Side (LS-FET) power MOSFETs to provide high efficiency without the need for an external Schottky diode. The device's Advanced Asynchronous Modulation (AAM) mode achieves high efficiency under light-load conditions by scaling down the frequency to reduce switching and gate driver losses. Typical applications include automotive infotainment systems, automotive lamps and LEDs, automotive motor control, and industrial power systems.
