The MP4321 is a configurable-frequency (350kHz to 2.5MHz), synchronous, step-down switching converter with integrated internal highside and low-side power MOSFETs (HS-FET and LS-FET, respectively). The device provides up to 1A of highly efficient output current (IOUT) with peak current control mode. The wide 3.3V to 36V input voltage (VIN) range and 42V load.
• Designed for Aftermarket Automotive Applications: o 42V Load Dump Tolerance o Supports 3.1V for Cold Crank Conditions o Up to 1A of Continuous Output Current o Wide 3.3V to 36V Operating Input Voltage (VIN) Range o -40°C to +125°C Operating Junction Temperature (TJ) Range
• Increases Battery Life: o 1μA Shutdown Current (ISD) o 20μA Sleep Mode Quiescent Current o Advanced Asynchronous Modulation (AAM) Mode for Increased Efficiency under Light Load Conditions
• High Performance for Improved Thermals: o 70mΩ/50mΩ Integrated MOSFETs o 65ns Minimum On Time (tON_MIN) o 50ns Minimum Off Time (tOFF.
