Monolithic Power Systems (MPS) MPM3820 Synchronous Step-Down Converters
Monolithic Power Systems (MPS) MPM3820 Synchronous Step-Down Converters achieve 2A continuous output current from a 2.7V to 6V input voltage with excellent load and line regulation. These converters feature built-in power MOSFETs and an inductor. Designers can use the devices to regulate output voltage as low as 0.6V. The constant-on-time control (COT) scheme provides a fast transient response, high light-load efficiency, and easy loop stabilization. Fault condition protection includes a cycle-by-cycle current limit and thermal shutdown (TSD). MPS MPM3820 Synchronous Step-Down Converters require a minimum number of readily available standard external components. These devices are offered in a small QFN-20 package, making them ideal for powering portable equipment operating from a single-cell lithium-ion battery.Features
