About This Product

■Summary

MPM38222 is a dual channel DC/DC module. The module is a step-down switch-mode converter with an internal power MOSFET and inductor. The MPM38222 is designed to simplify power system design and be easy to use. The MPM38222 operates from an input voltage of 2.7V to 6V, produces a low output voltage of 0.608V, and has a quiescent current of 45µA, making it ideal for powering portable equipment powered by single-cell lithium-ion (Li+) batteries. The MPM38222 integrates dual 80mΩ high-side switches and 35mΩ synchronous rectification to achieve high efficiency without the use of external Schottky diodes. Peak current mode control and internal compensation minimize the number of off-the-shelf external components. Complete protection features include cycle-by-cycle current limiting and thermal shutdown. The MPM38222 is available in a small, surface-mount QFN-14 (4mm x 4mm x 1.6mm) package.

■Features and benefits

・2A dual output current ・Peak efficiency over 93% ・Light load efficiency exceeding 80% ・Ultra-low self-consumption current: 45µA ・80mΩ and 35mΩ internal power MOSFETs ・Wide operating input range from 2.7V to 6V - 1MHz switching frequency by default ・180° phase shift operation ・100% duty cycle operation ・Cycle-by-cycle overcurrent protection (OCP) ・Hiccup mode short circuit protection (SCP) ・Thermal shutdown ・Available in small QFN-14 (4mmx4mmx1.6mm) package

■Available product numbers

・MPM38222GR-P MPM38222GR-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
