MPQ4345GLE-33-AEC1-P

MPQ4345GLE-33-AEC1-P is a 36V, 2A, ultra-low quiescent current, synchronous step-down converter with a 350KHz to 2.5MHz configurable frequency and an integrated internal high-side MOSFET (HS-FET) and low side MOSFET (LS-FET). The device provides up to 2A of highly efficient output current (IOUT) with fixed-frequency, zero-delay pulse-width modulation (PWM) control to optimize transient response. 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 quiescent current (IQ) in shutdown mode allows the device to be used in battery-powered applications. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency (fSW) under light-load conditions to reduce switching and gate driving losses. Typical applications are automotive clusters, automotive infotainment, advanced driver assistance systems (ADAS), industrial power systems.
