MPQ4360 Synchronous Step-Down Converters Monolithic Power Systems (MPS) MPQ4360 Synchronous Step-Down Converters offer a configurable frequency with integrated internal high-side and low-side power MOSFETs. The MPQ4360 delivers up to 6A of highly efficient output current (IOUT) with current mode control for fast loop response. The device provides a 3.3V to 40V wide input voltage (VIN) range facilitating a variety of step-down applications in automotive input environments. The 1.7μA shutdown current (ISD) permits the device to be used in battery-powered applications.
