MP4323
42V Load Dump Tolerant, 3A, Ultra-Compact, Low-IQ, Synchronous Step-Down Converter
DESCRIPTION
The MP4323 is a frequency-configurable (350kHz to 2.5MHz), synchronous, step-down switching converter with integrated internal highside and low-side power MOSFETs (HS-FET and LS-FET, respectively). It can achieve up to 3A of highly efficient output current (IOUT) with peak current control mode.
The wide 3.3V to 36V input voltage (VIN) range and 42V load dump tolerance accommodate a variety of step-down applications in automotive input environments. A 1μA shutdown current (ISD) allows the device to be used in batterypowered applications.
