1. DESCRIPTION

The MPM38111 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 MPM38111 is designed to simplify power system design and provide ease of use. The MPM38111 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 MPM38111 integrates dual, 85mΩ,high-side switches and 40mΩ 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 MPM38111 is available in a small, surfacemounted, QFN-14 (4mmx4mmx1.6mm) package.
