25MHz High Efficiency Synchronous Buck
Regulator
FN6858 Rev 2.
00 May 26, 2011
The ISL8088 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 the use of a single Li+ cell, three NiMH cells or a regulated 5V input.
The current mode control architecture enables very low duty cycle operation at high frequency with 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 gen...
