IC revision1.0

Description

The EVL1604-TL-00A evaluation board is designed to demonstrate the capabilities of the MP1604, a monolithic, step-down switch-mode converter with built-in, internal power MOSFETs. The MP1604 can achieve up to 4A of continuous output current (IOUT) across a 2.4V to 5.5V input voltage (VIN) range, with excellent load and line regulation. The output voltage (VOUT) can be regulated to as low as 0.4V.Constant-on-time (COT) control provides fast transient response, easy loop design, and tight output regulation. Full protection features include over-current protection (OCP), current limiting with hiccup mode, and thermal shutdown.The MP1604 requires a minimal number of readily available, standard external components, and is available in an ultra-small SOT583 package.
