The ISL9120IIN-EVZ and ISL9120IIA-EVZ platforms allow quick evaluation of the high-performance features of the ISL9120 buck-boost regulator. The ISL9120IIN-EVZ evaluates the ISL9120IINZ featuring fixed 3.3V output.

The ISL9120 is a highly integrated buck-boost switching regulators for systems using new battery chemistries in a 1.41mm x 1.41mm WLCSP 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.


  • Small, compact design
  • Jumper selectable EN (enabled/disabled)
  • Jumper selectable BYP (buck-boost/forced bypass)
  • Connectors, test points and jumpers for easy probing
  • Resistor programmable output voltage on the ISL9120IIA-EVZ
  • Fixed 3.3V output voltage on the ISL9120IIN-EVZ


  • Smartphones and tablets
  • Portable consumer and wearable devices
