DATASHEET ISL8002, ISL8002A, ISL80019, ISL80019A Compact Synchronous Buck Regulators FN7888 Rev 4.00 July 31, 2014 The ISL8002, ISL8002A, ISL80019 and ISL80019A are highly efficient, monolithic, synchronous step-down DC/DC converters that can deliver up to 2A of continuous output current from a 2.7V to 5.5V input supply. They use peak current mode control architecture to allow very low duty cycle operation. They operate at either 1MHz or 2MHz switching frequency, thereby providing superior transient response and allowing for the use of small inductors. They also have excellent stability and provide both internal and external compensation options. The ISL8002, ISL8002A, ISL80019 and ISL80019A integrate very low rDS(ON) MOSFETs in order to maximize efficiency.
