描述
The ISL8012EVAL1Z evaluation board provides a platform to evaluate the performance of the ISL8012 synchronous buck regulator.
Ideal for any low power, low voltage application, the ISL8012 is a high-efficiency, monolithic, synchronous step-down DC/DC converter that can deliver up to 2A of continuous output current from a 2.7V 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.
