The ISL854102DEMO3Z board uses the ISL854102 in an isolated buck-boost configuration. The board demonstrates an inverted primary output and a non-inverted secondary output. The board is configured for 5.5V to 40V input voltage range. The primary output is -5V capable of 500mA, and the +5V secondary output is capable of 500mA.


  • Wide input voltage range of 3.5V to 40V
  • Synchronous operation for high efficiency
  • Integrated high-side and low-side NMOS devices
  • Internal fixed (500kHz) or adjustable (300kHz to 2MHz) switching frequency
  • Continuous output current up to 0.5A at primary output and 0.5A at secondary output
  • Internal or external soft-start
  • Minimal external components required
  • Power-good and enable functions available



  • Industrial control
  • Medical devices
  • Portable instrumentation
  • Distributed power supplies
  • Cloud infrastructure
