Overview
Description
The ISL85413DEMO3Z demonstration 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 ISL85413DEMO3Z uses the ISL85413 synchronous buck regulator 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 ISL85413 is offered in a 3mm x 3mm 8 Ld TDFN package with a 1mm maximum height. The converter occupies 3.3cm² area.

See how easy it is to design with Intersil's new pin-for-pin compatible synchronous buck regulators with a wide input voltage range. With three different output current options, these highly efficient sync buck regulators simplify power circuit design and enable reuse of circuit board design across a wide range of end applications.
