ISL854102DEMO2Z, ISL854102DEMO3Z

Wide VIN 1.2A Synchronous Buck Regulator Demonstration Boards

Description

The ISL854102DEMO2Z board uses the ISL854102 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 4mmx3mm 12 Ld DFN package with 1mm maximum height.
