The ISL9120IIx-EVZ (ISL9120IIN-EVZ, ISL9120IIA-EVZ) and ISL9120IRx-EVZ (ISL9120IRN-EVZ and ISL9120IRA-EVZ) platforms allow quick evaluation of the high performance features of the ISL9120 and ISL9120IR buck-boost regulators.

The ISL9120 and ISL9120IR are highly integrated buck-boost switching regulators for systems using new battery chemistries. 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.


  • Small, compact design
  • Jumper selectable EN (enabled/disabled)
  • Jumper selectable BYP (buck-boost/forced bypass)
  • Connectors, test points and jumpers for easy probing


  • Smartphones and tablets
  • Portable consumer and wearable devices
