1.
2A High Efficiency Buck-Boost
Regulators
The ISL9110 and ISL9112 are highly-integrated buck-boost switching
regulators that accept input voltages either above or below the regulated output voltage.
Unlike other Buck-Boost
regulators, these
regulators automatically transition between operating modes without significant output disturbance.
Both parts are capable of delivering up to 1.
2A output current, and provide excellent efficiency due to their 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 ...
