Renesas Electronics ISL91110IRAZ-T7A, 1 Buck Boost, Buck Boost Regulator 4.5A, 1 → 5.2 V, 2.5 MHz 20-Pin, TQFN-20

The Renesas Electronics highly-integrated buck-boost switching regulator that accept input voltages either above or below the regulated output voltage. Unlike other buck-boost regulator, this regulator automatically transition between operating modes without significant output disturbance.

Automatic and seamless transitions between buck and boost modes
High efficiency up to 95%
Fully protected for overcurrent, over-temperature, and under voltage
Accepts input voltages above or below regulated output voltage
Selectable forced PWM mode and ex
