MPQ2143H

3A, 5.5V, 2.0MHz

Synchronous Step Down Switcher

DESCRIPTION

FEATURES

The MPQ2143H is a monolithic, step-down,

switch-mode 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 voltage can be regulated as low as 0.6V.



Wide 2.5V to 5.5V Operating Input Range

Output Voltage as Low as 0.6V

100% Duty Cycle in Dropout

Up to 3A Output Current

80mΩ and 40mΩ Internal Power MOSFET

Switches



Default 2.0MHz 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

Constant-on-time control provides fast transient

response and eases loop stabilization. Fault-

condition protections include cycle-by-cycle

current limiting and thermal shutdown.

The MPQ2143H is available in small QFN-10

package and requires only a minimal number of

readily-available standard external components.



Available in QFN-10 (2mmx3mm) Package

The MPQ2143H is ideal for a wide range of

applications including high-performance DSPs,

FPGAs, and portable instruments.

APPLICATIONS



Low Voltage I/O System Power

Handheld/Battery-powered Systems

Wireless/Networking Cards
