MP9143

3A, 5.5V, 1.2MHz, 40μA I_Q, COT

Synchronous Step Down Switcher

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP9143 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

Low I_Q: 40µA

80mΩ and 40mΩ Internal Power MOSFET

Switches

Constant-on-time control provides fast transient

response and eases loop stabilization. Fault-

condition protections include cycle-by-cycle

current limiting and thermal shutdown.



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 MP9143 is available in small TSOT23-8

package and requires only a minimal number of

readily-available standard external components.

The MP9143 is ideal for a wide range of

applications including high-performance DSPs,

FPGAs, smartphones, portable instruments,

and DVD drivers.



Available in a TSOT23-8 Package

APPLICATIONS



Low Voltage I/O System Power
