DATASHEET
ISL91107 FN8584
Rev 3.00
May 3, 2018 High Efficiency Buck-Boost Regulator with 3.6A Switches
The ISL91107 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 provides excellent efficiency
due to its fully synchronous 4-switch architecture. No-load
quiescent current of only 45ВµA also optimizes efficiency under
light-load conditions.
The ISL91107 is designed for standalone applications and
supports 3.3V fixed output voltages or variable output voltages
with an external resistor divider. Output voltages as low as 1V
or as high as 5.2V are supported using an external resistor
divider.
The ISL91107 requires only a single inductor and very few
external components. Power supply solution size is minimized
by a 2.15mmx1.51mm WLCSP and a 2.5MHz switching
frequency, which further reduces the size of external …
