C5 D4 A3 B3 C3 C4 EFFICIENCY (%) ISL9110A 1.2A High Efficiency Buck-Boost Regulator The ISL9110A is a highly-integrated Buck-Boost switching regulator that accepts input voltages either above or below the regulated output voltage. Unlike other Buck-Boost regulators, this regulator automatically transitions between operating modes without significant output disturbance. This part is capable of delivering up to 1.2A output current, and provides excellent efficiency due to its fully synchronous 4-switch architecture. No-load quiescent current of only 35µA also optimizes efficiency under light-load conditions. Forced PWM and/or synchronization to an external clock may also be selected for noise sensitive applications. The ISL9110A is designed for standalone applications and supports 3.
