Overview
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 provides excellent efficiency due to its fully synchronous 4-switch architecture.
No load quiescent current of only 27.
5µA also optimizes efficiency under light-load conditions.
Forced PWM and/or synchronization to an external clock may also be selected for noise sensitive applications.
The ISL91108 is designed for standalone applications and supports a 3.
3V fixed output voltage or variable output voltages with an external resistor divider.
Output voltages as low as 1V or as high as 5.
2V are support...
