描述
The ISL8009AEVAL1Z evaluation board is intended for use by individuals with requirements for point-of-load (POL) applications sourcing from 2.7V to 5.5V. The board demonstrates the performance of the ISL8009A low quiescent current mode converter.
The ISL8009A is offered in a 2mm x 3mm 8 Ld DFN package with 1mm maximum height. The complete converter occupies less than 1cm2 area.
