Product Description

The MPQ2451 is a high frequency, step-down, switching regulator with an integrated high-voltage high-side power MOSFET. It efficiently provides up to a 0.6A output 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 current allows use in battery-powered applications. The MPQ2451 achieves high power-conversion efficiency over a wide load range by scaling down the switching frequency under light-load condition to reduce the switching and gate driving losses. Frequency fold-back prevents inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. The MPQ2451 is available in a cost-effective SOT23-6L, TSOT23-6L and QFN-6L packages.

Kit details

The EVQ2451-G-00A is an evaluation board for the MPQ2451, a fixed 2MHz frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. The IC provides 0.6A output with current mode control for fast loop response and easy compensation.

High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at light load condition to reduce the switching and gate driving losses.

The soft-start function helps prevent inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation.

By switching at 2MHz, smaller value inductor and input/output capacitor can be used to lower down cost and save board space.
