ISL8002B
Compact Synchronous Buck Regulator
The ISL8002B is a highly efficient, 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 peak current mode control architecture to allow very low duty cycle operation. ISL8002B operates at a 2MHz switching frequency, thereby providing superior transient response and allowing for the use of a small inductor. ISL8002B also has excellent stability.
The ISL8002B integrates very low rDS(ON) MOSFETs in order to maximize efficiency. In addition, since the high-side MOSFET is a PMOS, the need for a boot capacitor is eliminated, thereby reducing external component count.
