ISL91107IRTAZ-T - Renesas Electronics

Description: The ISL91107IR 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 45µA also op
