MP4313 Synchronous Step-Down Converters

Monolithic Power Systems (MPS) MP4313 Synchronous Step-Down Converters offer a configurable frequency with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET). The device delivers up to 3A of highly efficient output current (IOUT) with current mode control for fast loop response. A wide 3.3V to 45V input voltage (VIN) range on the MP4313 allows a variety of step-down applications in automotive input environments. A high-duty cycle and low-dropout mode enable automotive cold-crank conditions. The MP4313 converters offer a 1.7μA shutdown current (ISD) for battery-powered applications.
