ISL85413DEMO3Z

300mA Synchronous Buck Regulator Demonstration Board

Description

The ISL85413DEMO3Z board uses the ISL85413 in an isolated buck configuration. It replaces the filter inductor with a coupled inductor (or transformer) to produce a primary output and an inverting secondary output.

The board is used to demonstrate the performance of the ISL85413 wide VIN low quiescent current, high efficiency, synchronous buck regulator to produce a positive primary output and a negative isolated secondary output.

The ISL85413 is offered in a 3mmx3mm 8 Ld TDFN package with 1mm maximum height. The converter occupies 3.3cm² area.
