MPQ2122

6V, 2A, Low Quiescent Current

Dual, SYNC Buck Regulator

The Future of Analog IC Technology

DESCRIPTION

FEATURES

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.

•

Dual 2A-Output Current

>93% Peak Efficiency

>80% Light-Load Efficiency

Wide 2.7V-to-6V Operating Input Range

80mΩ and 35mΩ Internal Power MOSFET

1MHz Fixed Switching Frequency

Adjustable Output from 0.608V to VIN

180° Phase-Shifted Operation

100% Duty-Cycle Operation

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.

45µA Quiescent Current

Cycle-by-Cycle Over-Current Protection

Short-Circuit Protection with Hiccup Mode

Thermal Shutdown

Available in an 8-pin TSOT23-8 Package

Fault-condition protections include cycle-by-cycle

current limiting and thermal shutdown.
