MP4317 Synchronous Step-Down Converters Monolithic Power Systems (MPS) MP4317 Synchronous Step-Down Converters offer a configurable frequency with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET). The MP4317 delivers up to 7A of highly efficient output current (IOUT) with current mode control for fast loop response. The device provides a 3.3V to 45V wide input voltage (VIN) range facilitating a variety of step-downapplications in automotive input environments. A high duty cycle and low-dropout mode are available on the MP4317 allowing for automotive cold-crank conditions. Additionally, the 1.7μA shutdown current (ISD) permits the device to be used in battery-powered applications.
