MPQ2143-AEC1

MPQ2143-AEC1

AEC1-Automotive Grade, 3A, 5.5V, 1.2MHz, 40μA I_Q, COT Synchronous Step-Down Switcher

Datasheet

Description

The MPQ2143 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.
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 MPQ2143 is available in small TSOT23-8 package and requires only a minimal number of readily-available standard external components.
The MPQ2143 is ideal for a wide range of applications including high-performance DSPs, FPGAs, smartphones, portable instruments, and DVD drivers.

Evaluation Tools

EV2143H-D-00A Evaluation Kit 3A, 5.5V, 2MHz Synchronous Step-Down Switcher Evaluation Board

The EV2143H-D-00A is used for demonstrating the performance of MPS’s MP2143H, a monolithic, step-down, switch-mode converter with internal power MOSFETs. It can achieve up to 3A of continuous output current from a 2.5V to 5.5V input voltage range, with excellent load and line regulation. The output voltage can be regulated as low as 0.6V.

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 MP2143H is ideal for wide range of applications including high-performance DSPs, FPGAs, portable instruments, and automotive power systems.

The MP2143H is available in a QFN-10 package.

EV2143H-D-00A contains two different layouts, a tiny one and a normal one. They will work with different thermal performances.
