The MPQ2451-5/33 is a high-frequency, stepdown, switching regulator with an integrated,high-voltage, high-side power MOSFET. It efficiently outputs up to 0.6A, with current-mode control for fast loop response. The wide 3.3V-to-36V input range accommodates a variety of automotive step-down applications, and the 3μA shutdown-mode quiescent currentallows use in battery-powered applications.The MPQ2451-5/33 achieves high powerconversion efficiency over a wide load range by scaling down the switching frequency underlight-load conditions to reduce switching and gate driving losses. Frequency fold-back prevents inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation.The MPQ2451-5/33 is available in cost-effective SOT23-6L and QFN-6L packages
