Beschreibung

The EV2158A-QH-00A is used for demonstrating the performance of MPS’s MP2158A, a low voltage high switching frequency step-down switcher with built in power MOSFETs. MP2158A provides up to 1A highly efficient output with constant-on-time control for fast loop response. MP2158A 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
