概要

The MP2122 is an internally-compensated, 1MHz fixed-frequency, dual PWM, synchronous, step-down regulator. The MP2122 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 MP2122 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 MP2122 is available in an 8-pin TSOT23-8 package.

Evaluation Tools

EV2122-J-00A Evaluation Kit 6V, Dual 2A, Low Quiescent Current SYNC Buck Regulator

The EV2122-J-00A is used for demonstrating the performance of MPS’s MP2122, an internally compensated, 1MHz, fixed-frequency, dual-PWM, synchronous step-down regulator.

The MP2122 is ideal for powering portable equipment that runs from a single-cell, Lithium-Ion (Li+) battery due to 45µA low quiescent current. The output voltage can be regulated as low as 0.608V.

With peak current mode control and internal compensation, the MP2122 requires a minimal number of readily available, standard external components, and is available in an 8-pin, TSOT23 package.
