MPQ4572 Synchronous Buck Converters

Monolithic Power Systems (MPS) MPQ4572 Synchronous Buck Converters are fully integrated, fixed-frequency synchronous step-down converters. These converters achieve up to 2A of continuous output current with peak current control for excellent transient response. The MPQ4572 series integrates internal high- and low-side power MOSFETs for high efficiency without an external Schottky diode. These converters employ advanced asynchronous modulation (AAM) to achieve high efficiency during light load conditions by scaling down the frequency to reduce switching and gate driver losses. Other features include built-in soft-start, enable control, power good indication, high-duty cycle, and a low-dropout mode for automotive cold crank conditions. MPS MPQ4572 converters offer a wide 4.5V to 60V input voltage range that accommodates a variety of step-down applications in an automotive input environment. Applications include automotive and industrial.
