Description

General part information

ISL91106A Series

The ISL91106 and ISL91106A 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 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.

The ISL91106 and ISL91106A are designed for standalone applications. They support 3.3V and 3.4V fixed output voltages or variable output voltages with an external resistor divider.
