APPLICATION NOTE 4363 Vacuum Fluorescent Display (VFD) Reference Design for Automotive Applications
Mar 26, 2009
Abstract: This article describes a vacuum fluorescent display (VFD) and some ideal applications for the technology. The reference design then shows how to use a power-supply controller in a flyback topology to obtain multiple output voltages for a vacuum fluorescent display.
This reference design shows a solution for obtaining the drive voltage required for a vacuum fluorescent display (VFD) power supply in automotive applications. The design includes the complete schematic, and presents the bill of materials (BOM), load/ line regulation measurements, and test results.
