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.
