ISL91107IR Buck-Boost Regulator
Renesas Electronics ISL91107IR Buck-Boost Regulator 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, the ISL91107IR 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. A no-load quiescent current of only 45μA also optimizes efficiency under light load conditions. The ISL91107IR 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.
