MPQ4323C 42V Load Dump Tolerant, 3A, Ultra-Compact, Synchronous Step-Down Converter, AEC-Q100 Qualified DESCRIPTION The MPQ4323C is a configurable-frequency (350kHz to 2.5MHz), synchronous, step-down switching regulator with integrated internal highside and low-side power MOSFETs. The device provides 3A of highly efficient output current (IOUT) with peak current mode control. The wide 3.3V to 36V input voltage (VIN) range and 42V load dump tolerance accommodates a variety of step-down applications in automotive input environments. A 1μA shutdown mode quiescent current allows use in battery-powered applications. An open-drain power good (PG) signal indicates that the output is within 94.5% to 105.5% of its nominal voltage.
