The ISL854102DEMO2Z demo board uses the ISL854102 synchronous buck regulator in an isolated buck configuration. The primary output is configured to be 12V and the dual secondary outputs are +12V and -12V, respectively. The board is used to demonstrate the performance of the ISL854102 wide VIN synchronous buck regulator configured to support a primary output, and a dual inverting and non-inverting secondary output.

The ISL854102DEMO3Z board uses the ISL854102 in an isolated buck-boost configuration. The primary output is configured to be -5V and the secondary output is +5V. The board is used to demonstrate the performance of the ISL854102 wide VIN synchronous buck regulator, configured as a buck-boost converter to support an inverting primary output and a non-inverting secondary output.

The ISL854102 is the higher current version of the family of ISL85410 (1A), ISL854102 (1.2A), and ISL85418 (0.8A), which are offered in a 4mm x 3mm 12 Ld DFN package with 1mm maximum height.
