ISL8088, Dual 800mA Low Quiescent Current 2.25MHz High Efficiency Synchronous Buck Regulator
DFN SYMBOL DESCRIPTION 1 FB1 The feedback network of the Channel 1 regulator.
FB1 is the negative input to the transconductance error amplifier.
The output voltage is set by an external resistor divider connected to FB1.
With a properly selected divider, the output voltage can be set to any v
DATASHEET ISL8088 Dual 800mA Low Quiescent Current 2.25MHz 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 f
