MP2141Q Datasheet Synchronous Step-down Converter

Manufacturer: Monolithic Power Systems

Overview: The Future of Analog IC Technology MP2141Q 1.5A, Synchronous Step-Down Converter with VSEL.

General Description

The MP2141Q is a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs.

The MP2141Q achieves 1.5A of continuous output currents from a 2.3V to 5.5V input voltage with excellent load and line regulation.

The constant-on-time (COT) control scheme provides fast transient response and eases loop stabilization.
