ISL8088 Synchronous Buck Regulator

Renesas Electronics ISL8088 Synchronous Buck Regulator is a high-efficiency, dual synchronous step-down DC-DC regulator that can deliver up to 800mA continuous output current per channel. The supply voltage range of 2.75V to 5.5V allows using a single Li+ cell, three NiMH cells, or a regulated 5V input. The current mode control architecture enables very low-duty cycle operation at a high frequency with a fast transient response and excellent loop stability. The ISL8088 operates at 2.25MHz switching frequency allowing the use of small, low-cost inductors and capacitors. Each channel is optimized for generating an output voltage as low as 0.6V.
