The MPQ2454GQ-AEC1-Z is a frequency-programmable (350kHz to 2.3MHz) step-down switching regulator with an integrated internal high-side, high-voltage power MOSFET. It outputs efficiently up to 0.6A and has current-mode control for fast loop response.The wide 3.3V to 36V input range accommodates a variety of step-down applications in automotive-input environments. A 3.5μA shutdown-mode quiescent current allows for use in battery-powered applications. Also, the device has a high duty cycle and low drop-out mode for automotive cold-crank conditions.The MPQ2454GQ-AEC1-Z achieves high-power conversion efficiency over a wide load range by scaling down the switching frequency at light-load conditions to reduce both switching and gate driving losses.Frequency foldback prevents inductor current runaway during start-up and short circuit. Thermal shutdown provides reliable, fault-tolerant operation. An open-drain power good (PG) signal indicates when the output is within its nominal voltage.The MPQ2454GQ-AEC1-Z is available in MSOP-10 EP and QFN-10 (3mmx3mm) packages. 9icnet Electronics is an authorized Monolithic Power Systems distributor.
