DATASHEET ISL91107IR High Efficiency Buck-Boost Regulator with 4.1A Switches FN8687 Rev 0.00 March 2, 2015 The ISL91107IR 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 provi
