Product Description

The EV2454-H-00A is an evaluation board for the MP2454/MPQ2454, a frequency-programmable (350kHz to 2.3MHz) step-down switching regulator with integrated internal high-side high voltage power MOSFET. It efficiently outputs 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 3.5μAshutdown-mode quiescent current allows for use in battery-powered applications. The device also has a high-duty cycle and low drop-out mode for automotive cold-crank conditions.

The MPQ2454 also 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 fold-back prevents inductor current runaway during start-up andshort circuit. Thermalshutdown provides reliable, fault-tolerant operation. An open-drain power-good signal indicates the output is within its nominal voltage.

The EV2454-H-00A is assembled and tested with MSOP-10 package.

IC Details

The MPQ2454 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 MPQ2454 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 MPQ2454 is available in MSOP-10 EP and QFN-10 (3mmx3mm) packages.
