ISL9120 Overview
DATASHEET ISL9120 pact High Efficiency Low Power Buck-Boost Regulator FN8659 Rev.3.00 Nov 29, 2018 The ISL9120 is a highly integrated buck-boost switching regulator that accepts input voltages either above or below the regulated output voltage. This regulator automatically transitions between buck and boost modes without significant output disturbance. The ISL9120 also has automatic bypass functionality.
