The ISL8014AEVAL2Z evaluation board is intended for use by individuals with requirements for point-of-load (POL) applications sourcing from 2.7V to 5.5V. This evaluation board demonstrates the performance of the ISL8014A low quiescent current mode converter.

The ISL8014A is a high-efficiency, monolithic, synchronous step-down DC/DC converter that can deliver up to 4A of continuous output current from a 2.8V to 5.5V input supply. It uses a current control architecture to deliver very low duty cycle operation at high frequency with fast transient response and excellent loop stability.
