A8504938S25A - Brand New Amphenol PCD Backshells and Cable Clamps
-
Description
The A8504938S25A is a model of backshells and cable clamps used to provide protection and strain relief for cables in electronic equipment. It is a multi-output WLED driver for medium display backlighting, integrating a boost converter and eight current sinks to provide a WLED/RGB backlight driver. The boost converter can provide output voltage up to 47 V, allowing a wide range of LED backlight applications for thin notebook displays, LCD TVs, RGB backlights, GPS systems, portable DVD players, and more.
