The Future of Analog IC Technology DESCRIPTION The MPQ2122 is an internally-compensated, 1MHz fixed-frequency, dual PWM, synchronous, step-down regulator. The MPQ2122 operates from a 2.7V-to-6V input, generates an output voltage as low as 0.608V, and has a 45µA quiescent current that makes it ideal for powering portable equipment that runs on a single cell lithium-ion (Li+) battery. The MPQ2122 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 limits the minimum number of readily-available external components. Fault-condition protections include cycle-by-cycle current limiting and thermal shutdown. The MPQ2122 is available in an 8-pin TSOT23-8 package.
