MPQ4334 36V, 0.5A to 4A, Low Quiescent Current, Synchronous Step-Down Converter, AEC-Q100 Qualified DESCRIPTION The MPQ4334 is a configurable-frequency (200kHz to 2.5MHz), synchronous, step-down switching regulator with integrated internal highside and low-side power MOSFETs (HS-FET and LS-FET, respectively). The device provides 0.5A to 4A of highly efficient output current (IOUT) with peak current mode control. The wide 3V to 36V input voltage (VIN) range and 40V load dump tolerance accommodates a variety of step-down applications in automotive input environments. A 0.5μA shutdown current (ISD) allows the device to be used in batterypowered applications.
