Description

he EV2184-TL-00A is an evaluation board designed to demonstrate the capabilities of the MP2184, a monolithic, step-down switch-mode converter with built-in internal power MOSFETs. It achieves up to 4A of continuous output current (IOUT) across a 2.5V to 5.5V input voltage (VIN) range, with excellent load and line regulation. The output voltage (VOUT) can be regulated to as low as 0.6V.Constant-on-time (COT) control provides fast transient response and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown.The MP2184 is ideal 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 MP2184 requires a minimal number of readily available, standard external components, and it is available in an ultra-small SOT583 package.
