MPM38222GR-Z

MPM38222 Dual 2A, 2.7V-6V, Power Module, Synchronous, Step-Down Converter with Integrated Inductors DESCRIPTION FEATURES The MPM38222 is a dual-channel DC/DC module. The module includes a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs and inductors. The MPM38222 is designed to simplify power system design and provide ease of use.           The MPM38222 operates from a 2.7V to 6V input, generates an output voltage as low as 0.608V, and has a 45µA quiescent current, making it ideal for powering portable equipment that run on a single-cell Lithium-ion (Li+) battery. The MPM38222 integrates dual, 80mΩ, high-side switches and 35mΩ synchronous rectifiers for high efficiency without an external Schottky diode. Peak-current-mode control and internal compensation limit the minimum number of readily available external components. Full protection features include cycle-by-cycle current limiting and thermal shutdown. The MPM38222 is available in a small, surfacemounted, QFN-14 (4mmx4mmx1.6mm) package.    Dual 2A Output Current >93% Peak Efficiency >80% Light-Load Efficiency Ultra-Low IQ: 45μA 80mΩ and 35mΩ Internal Power MOSFET Wide 2.7V to 6V Operating Input Range Default 1MHz Switching Frequency 180° Phase-Shifted Operation 100% Duty Cycle Operation Cycle-by-Cycle Over-Current Protection (OCP) Short-Circuit Protection (SCP) with Hiccup Mode Thermal Shutdown Available in a Small QFN-14 (4mmx4mmx1.6mm) Package APPLICATIONS      Optical Modules Industrial Products IoT Devices LDO Replacements Medical Devices All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
