The MPM3830 is a monolithic step-down switch mode converter with built-in internal power MOSFETs and inductor. The DC-DC module has a small surface mount 3mm x 5mm x 1.6mm QFN package. It achieves 3A continuous output current from a 2.7V to 6V input voltage with excellent load and line regulation. The MPM3830 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) Battery. The output voltage can be regulated as low as 0.6V. Only input, output capacitors and FB resistors are needed to complete the design. The Constant-On-time (COT) control scheme provides fast transient response, high light­load efficiency and easy loop stabilization. Fault condition protection includes cycle­by­cycle current limit and thermal shutdown. The MPM3830 requires a minimum number of readily available standard external components and is available in an ultra-small QFN20 (3mmx5mm) package.
