The EV2457-T-00A evaluation board is designed to demonstrate the capabilities of MPS’s 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 foldback 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.
