DATASHEET ISL8012 2A Low Quiescent Current 1MHz High Efficiency Synchronous Buck Regulator FN6616 Rev 2.00 December 1, 2011 The ISL8012 is a high efficiency, monolithic, synchronous step-down DC/DC converter that can deliver up to 2A 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.

The ISL8012 integrates a pair of low ON-resist

ISL8012 Features

* include internal soft-start, internal compensation, overcurrent protection, and thermal shutdown. The ISL8012 is offered in a space saving 3mmx3mm 10 Ld DFN package lead free package with exposed pad lead frames for low thermal. The complete converter occupies less than 0.35in2 area. Features
