MPQ4347/4347J 36V, 4A, Ultra-Low Quiescent Current, Synchronous Step-Down Converter, AEC-Q100 Qualified DESCRIPTION The MPQ4347/4347J is a configurablefrequency (350kHz to 2.5MHz), synchronous, step-down switching regulator with an integrated internal high-side and low-side MOSFET (HSFET and LS-FET, respectively). The device provides 4A of highly efficient output current (IOUT) with fixed-frequency, zero-delay pulsewidth modulation (PWM) control to optimize transient response. The wide 3.3V to 36V input voltage (VIN) range with 42V load dump support accommodates a variety of step-down applications in an automotive input environment. The 1μA shutdown mode quiescent current allows the device to be used in battery-powered applications.
