DATASHEET ISL91108 High Efficiency Buck-Boost Regulator with 4.2A Switches FN8448 Rev 1.00 November 12, 2014 The ISL91108 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 2.7A of burst current (PVIN = 3V, VOUT = 3.3V), and provi
ISL91108 Features
* Accepts input voltages above or below regulated output voltage
* Automatic and seamless transitions between buck and boost modes
* Input voltage range: 1.8V to 5.5V
* Output current: up to 1.6A DC (PVIN = 2.8V, VOUT = 3.3V)
* Burst current: up to 2.7A (PVIN
