DESCRIPTION The MP4316 is a frequency-configurable, synchronous, step-down switching converter with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). It can achieve up to 6A of highly efficient, continuous output current (IOUT) with current control mode for fast loop response. The wide 3.3V to 45V input voltage (VIN) range accommodates a variety of step-down applications in an automotive input environment. The device’s 1.7μA shutdown current (ISD) makes it ideal for battery-powered applications. The MP4316 provides high power conversion efficiency across the entire load range.
