The ISL9120IRN-EVZ and ISL9120IRA-EVZ platforms allow quick evaluation of the high-performance features of the ISL9120IR buck-boost regulator. The ISL9120IRA-EVZ evaluates the ISL9120IRAZ featuring resistor programmable output voltage.

The ISL9120IR is a highly integrated buck-boost switching regulators for systems using new battery chemistries in a 3mm x 3mm 12 Ld TQFN package. They use Renesas' proprietary buck-boost algorithm to maintain voltage regulation while providing excellent efficiency and very low output voltage ripple when the input voltage is close to the output voltage.
