High Efficiency High Current Buck-Boost Regulator with Bypass Mode
Rev 2.00
November 20, 2015
The ISL91106 and ISL91106A are highly integrated buckboost switching regulators that accept input voltages either above or below the regulated output voltage. Unlike other buck-boost regulators, these regulators automatically transitions between operating modes without significant output disturbance. The devices also include a selectable bypass mode for low power consumption in applications that have a sleep or low-power mode.
These devices are capable of delivering up to 2A of output current (PVIN = 2.8V, VOUT = 3.3V) and provide excellent efficiency due to their fully synchronous 4-switch architecture. No load quiescent current of only 45µA also optimizes efficiency under light-load conditions.
