Monolithic Power Systems MPQ2166
The MPQ2166 is an internally compensated, dual, PWM, synchronous, step-down regulator that operates from a 2.7V to 6V input and generates an output voltage as low as 0.6V. The MPQ2166 can be configured as a 2A/2A or 3A/1A output current regulator and is ideal for powering portable equipment that runs on a single-cell lithium-ion (Li+) battery due to a low 60µA quiescent current. The MPQ2166 integrates dual, 55mΩ, high-side switches and 20mΩ synchronous rectifiers for high efficiency without an external Schottky diode.| Part No. | MPQ2166 |

DESCRIPTION
The MPQ2166 has peak-current-mode control and internal compensation and is capable of low dropout configurations when the part works in AAM mode. Both channels can operate at 100% duty cycle. Full protection features include cycle-by-cycle current limit and thermal shutdown. The MPQ2166 requires a minimum number of readily available, standard, external components and is available in QFN-18 (2mmx3mm) and QFN-18 (2.5mmx3.5mm) packages.
