The MPM3830 is a step-down module converter with built-in power MOSFETs and inductor. The DC-DC module comes in a small surface-mount QFN-20(3mm x 5mm x 1.6mm) package and 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 LithiumIon (Li+) Battery. The output voltage is regulated as low as 0.6V. Only FB resistors and input and output capacitors are needed to complete the design. The Constant-on-time control (COT) scheme provides fast transient response, high light-load efficiency and easy loop stabilization. Fault condition protection includes cycle-by-cycle current limit and thermal shutdown (TSD). The MPM3830 requires a minimum number of readily available standard external components and is available in an ultra-small QFN20 (3mmx5mm) package.Wide 2.7V to 6V Operating Input Range Adjustable Output from 0.6V 3.0mm x 5.0mm x 1.6mm QFN Package Total Solution Size 8.5mm x 4.5 mm Low Radiated Emissions (EMI) Complies with EN55022 Class B Standard Up to 3A Continuous Output Current 100% Duty Cycle in Dropout Ultra Low IQ: 40µA EN and Power Good for Power Sequencing Cycle-by-Cycle Over-Current Protection Short-Circuit Protection with Hiccup Mode Adjustable Output Only Needs 4 External Components : 2 Ceramic Capacitors and FB Divider Resistors
