DATASHEET ISL9120 Compact 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. When the input voltage is generally within 1% to 2% of the output voltage, there will .

ISL9120 Features

* Accepts input voltages above or below regulated output voltage

* Automatic bypass mode functionality

* Automatic and seamless transitions between buck and boost modes

* Input voltage range: 1.8V to 5.5V

* Selectable forced bypass power saving mode
