MP2166

6V, Dual 2A/2A or 3A/1A,

Low Quiescent Current,

Synchronous Buck with PG and SS

DESCRIPTION

FEATURES

The MP2166 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 MP2166

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.

 2.7V to 6V Operating Input Range

 2A/2A or 3A/1A Continuous Current

 55mΩ/20mΩ R_DS(ON)

 Programmed Frequency up to 3MHz

 External Sync Clock Up to 3MHz

 180^oPhase Shifted Operation

 PG Indicators

 External SS and Track

 Adjustable Advanced Asynchronous Mode

(AAM) or Forced Continuous Conduction

Mode (CCM)

The MP2166 integrates dual, 55mΩ, high-side

switches and 20mΩ synchronous rectifiers for

high efficiency without an external Schottky

diode. The MP2166 has peak-current-mode

control and internal compensation and is

capable of low dropout configurations. Both

channels can operate at 100% duty cycle.

 Peak Efficiency >90%

 Output Adjustable from 0.6V to VIN

 100% Duty Cycle Operation

 60µA Quiescent Current

 Cycle-by-Cycle

(OCP)

Over-Current

Protection

Full protection features include cycle-by-cycle

current limit and thermal shutdown.

 Short-Circuit Protection (SCP) with Hiccup

Mode and Valley Current Detection

 Thermal Shutdown

 Available in QFN-18 (2mmx3mm) and QFN-

18 (2.5mmx3.5mm) Packages

The MP2166 requires a minimum number of

readily available, standard, external components

and is available in QFN-18 (2mmx3mm) and

QFN-18 (2.5mmx3.5mm) packages.

APPLICATIONS
