The ISL80019 and ISL80019A evaluation kits are intended for use by individuals with requirements for point-of-load applications sourcing from 2.7V to 5.5V. The ISL80019 and ISL80019A evaluation boards are used to demonstrate the performance of the ISL80019 and ISL80019A, low quiescent, current high-efficiency synchronous buck regulators.

The ISL80019 and ISL80019A are offered in a 2mm x 2mm 8 Ld μTDFN package with a 1mm maximum height. The complete area that the converter occupies can be as small as 0.10in2.
