MP2187

Dual 3A, 5.5V, 1.2MHz, COT

Synchronous Step-Down Switcher

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2187 is a monolithic, step-down, switch-

mode dual converter with internal power

MOSFETs. It can achieve up to 3A continuous

output current from a 2.5V–to-5.5V input

voltage with excellent load and line regulation.

The output voltages of two channels are 1.1V

and 1.8V respectively.

•

Wide 2.5V-to-5.5V Operating Input Range

Fixed Output Voltages: 1.1V & 1.8V

100% Duty Cycle in Dropout

Up to 3A Output Current

Low IQ: 80µA

60mΩ and 30mΩ Internal Power MOSFET

Switches

•

Input Voltage Failure Indicator

Default 1.2MHz Switching Frequency

EN and Power-Good for Power Sequencing

Cycle-by-Cycle Over-Current Protection

Auto Discharge at Power-Off

Short-Circuit Protect with Hiccup Mode

Stable with Low-ESR Output Ceramic

Capacitors

The constant-on-time control scheme provides

fast transient response and eases loop

stabilization. Fault condition protections include

cycle-by-cycle current limiting, input voltage

failure indicator and thermal shutdown.

The

MP2187

available

small

2.2mmx2.6mm QFN16 package and requires

only a minimal number of readily available

standard external components.

•

Available in a 2.2mm x 2.6mm QFN16

Package

The MP2187 is ideal for a wide range of

applications including high-performance DSPs,

FPGAs, smart phones, portable instruments,

and DVD drivers.

APPLICATIONS
