MP2143 Datasheet (MPS) - COT Synchronous Step Down Switcher

MP2143, COT Synchronous Step Down Switcher

The MP2143 is a monolithic, step-down, switchmode converter with internal power MOSFETs.

It can achieve up to 3A continuous output current from a 2.5V *to-5.5V input voltage with excellent load and line regulation.

The output voltage can be regulated as low as 0.6V.
