Renesas ISL9123II EVZ Series Manual

ISL9123IIx-EVZ, ISL9123IRx-EVZ
The ISL9123IIx-EVZ and ISL9123IRx-EVZ evaluation
boards provide a platform for evaluating the
high-performance features of the ISL9123 buck
regulator. The ISL9123
switching regulator that accepts input voltages above
the regulated output voltage. It features a remarkably
low quiescent current consumption, excellent
2
efficiency, and an I C interface that allows you to
access its internal registers for output voltage and
operation mode control.
