MPM3820GQV-Z

MPM3820 The Future of Analog IC Technology 6V Input, 2A Module Synchronous Step-Down Converter with Integrated Inductor DESCRIPTION FEATURES The MPM3820 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 2A continuous output current from a 2.7V to 6V input voltage with excellent load and line regulation. The MPM3820 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 MPM3820 requires a minimum number of readily available standard external components and is available in an ultra-small QFN-20 (3mmx5mm) package. • • • • • • • Wide 2.7V to 6V Operating Input Range Adjustable Output from 0.6V 3.0mm x 5.0mm x 1.6mm QFN-20 Package Total Solution Size 8.5mm x 4.5 mm Low Radiated Emissions (EMI) Complies with EN55022 Class B Standard Up to 2A 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 APPLICATIONS • • • • • Low Voltage I/O System Power LDO Replacement Power for Portable Products Storage (SSD/HDD) Space-Limited Applications All MPS parts are lead-free and adhere to the RoHS directive.
