Monolithic Power Systems EV2143-J-00A

Description

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

MP2143 is ideal for powering portable equipment that runs from a single cell Lithiumion (Li+) Battery. The output voltage can beregulated 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 switchingrelated loss by constant on time control. Shortcircuit and thermal shutdown provides reliable, fault-tolerant operation.

MP2143 is available in TSOT23-8 package.
