Monolithic Power Systems MP2162A | Demoboard EV2162A-QH-00A

Description

The EV2162A-QH-00A is used for demonstrating the performance of MPS’s MP2162A, a low voltage high switching frequency step-down switcher with built in power MOSFETs. MP2162A provides up to 2A highly efficient output with constant-on-time control for fast loop response. MP2162A is ideal for powering portable equipment that runs from a single cell Lithiumion (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 provides reliable, fault-tolerant operation.
