The MPM38222 high-performance 6V input, dual-channel 2A power module is ideal for optical modules and other space-constrained applications. With a size of only 9mmx7mm and an efficiency of up to 90%, the dual-way 2A overall solution meets the EN55022 Class B standard and is packaged in a small QFN-14 (4mmx4mmx1.6mm) package.
Typical application
Packing Reference
The module includes a single chip step-down switching converter with a built-in internal power MOSFET and inductor. MPM38222 can simplify the design of the power supply system, easy to use. The MPM38222 can achieve output voltage as low as 0.608V in the input voltage range of 2.7V to 6V and has a static current of 45µA, making it ideal for single lithium-ion (Li+) battery-powered portable products.
Block diagram
The MPM38222 integrates a dual 80mΩ up-tube and a 35mΩ synchronous rectifier, eliminating the need for an external Schottky diode for greater efficiency. The peak current control mode and internal compensation minimize the number of existing external components used. Comprehensive protection features include weekly term current protection and overtemperature shutdown protection.
