Product Description

The EV2457-T-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP2457, a high-frequency, step-down, switching regulator with integrated high-side and low-side power MOSFETs designed specifically for power meter applications. The MP2457 can provide up to 0.6A of output current efficiently with current-mode control for fast loop response.

The wide 5V to 36V input range accommodates a variety of power meter step-down applications, and the 0.6μA shutdown mode quiescent current allows the device to be used in battery-powered applications. The MP2457 uses high duty cycle and low dropout mode for low power meter input voltage conditions.

Frequency fold-back prevents short circuit and inductor current runaway during start-up. Thermal shutdown provides reliable and fault-tolerant operation. The MP2457 is available in a cost-effective TSOT23-6 package.

The MP2457 is a high-frequency, step-down, switching regulator with integrated high-side and low-side power MOSFETs. The MP2457 can provide up to 0.6A of output current efficiently with current-mode control for fast loop response.

The wide 5V to 36V input range accommodates a variety step-down applications, and the 0.6μA shutdown mode quiescent current allows the device to be used in battery-powered applications. The MP2457 uses high duty cycle and low dropout mode for low input voltage conditions.

The MP2457 achieves high power conversion efficiency over a wide load range by scaling down the switching frequency under light-load conditions to reduce switching and gate driving losses.

Frequency foldback prevents short circuit and inductor current runaway during start-up. Thermal shutdown provides reliable and fault-tolerant operation.
