MP2194

5.5V, 4A, Synchronous Step-Down Converter with Low 4.5μA I_Q in SOT583 Package

MPL

Description

MPL

Optimized Performance with MPS Inductor

The MP2194 is a monolithic, step-down, switch-mode converter with built-in internal power MOSFETs. It achieves up to 4A of continuous output current (I_OUT) from a 2.4V to 5.5V input voltage (V_IN) range, with excellent load and line regulation. The output voltage (V_OUT) can be regulated to as low as 0.4V.

The constant-on-time (COT) control scheme provides fast transient response and facilitates loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown.

The MP2194 is well-suited for a wide range of applications, including high-performance digital signal processors (DSPs), wireless power, portable and mobile devices, and other low-power systems.

The MP2194 requires a minimal number of readily available, standard external components. It is available in an ultra-small SOT583 package.
