MPM3551CGQWE-AEC1-P

MPM3551CGQWE-AEC1-P is an easy-to-use, fully integrated, synchronous step-down power module with a built-in inductor and MOSFET switches. It can achieve up to 3A of continuous output current (IOUT), with excellent load and line regulation. 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 mode quiescent current (IQ) allows the device to be used in battery-powered applications. An open-drain power good (PG) signal indicates whether the output is within 94.5% to 105.5% of its nominal voltage. Frequency foldback helps prevent inductor current (IL) runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. A high-duty cycle and low-dropout (LDO) mode are provided for automotive cold crank conditions. Application includes automotive infotainment, automotive clusters, advanced-driver assistance systems, industrial power systems.
