ISL80031ADEMO1Z: 1.8V @ 3A, 2.7 ~ 5.5 Vin

Summary

The ISL80031ADEMO1Z board provide a simple platform to evaluate the performance of the ISL80031A low quiescent current mode converter.

This device is a highly efficient, monolithic, synchronous step-down DC/DC converter that can deliver up to 3A of continuous output current from a 2.7V to 5.5V input supply. The ISL80031A uses peak current mode control architecture to allow very low duty cycle operation. The device operate at a 2MHz switching frequency, thereby providing superior transient response and allowing for the use of small inductors.

The boards are offered in an 8 Ld 2mm x 2mm DFN package with 1mm maximum height. The complete converter occupies less than 64mm2 area.
