Renesas ISL9122AIIN-EVZ Manual

ISL9122AIIN-EVZ, ISL9122AIRN-EVZ
The ISL9122AIIN-EVZ and ISL9122AIRN-EVZ
platform allows quick evaluation of the high-
performance features of the
regulator. The ISL9122A is a highly integrated non-
inverting buck-boost switching regulator that accepts
input voltages both above or below the regulated
output voltage. It features an extremely low quiescent
current consumption, excellent efficiency and an I
interface that allows you to access its internal
registers, for output voltage and operation mode
control.
