DATASHEET ISL91107 High Efficiency Buck-Boost Regulator with 3.6A Switches FN8584 Rev 3.00 May 3, 2018 The ISL91107 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 device is capable of delivering up to 2A of output current (PVIN = 2.8V, VOUT = 3.3V) and provides ex.
