The EV2143-J-00A is used for demonstrating the performance of MPS’s the MP2143, a low-voltage, high switching frequency, step-down switcher with built-in power MOSFETs. The MP2143 provides up to 3A highly efficient output with constant-on-time control for fast loop response.

The MP2143 is ideal for powering portable equipment that runs from a single-cell Lithium-ion (Li+) Battery. The output voltage can be regulated as low as 0.6V.

High power efficiency over a wide load range is achieved by scaling down the switching frequency at light load to reduce the switching related loss by constant-on-time control. Short-circuit and thermal shutdown protections provide reliable, fault-tolerant operation.

The MP2143 is available in a TSOT23-8 package.
