VFD Grid/Anode Supply Using MAX6850-MAX6853 PUMP Output


要約: This note describes how to use the PUMP clock output of the MAX6850, MAX6851, MAX6852, or MAX6853 vacuum fluorescent display controllers to construct a low-cost boost converter. The dc-dc converter generates the high-voltage grid supply anode supply for the VFD tube from the 3.3V supply used by the MAX6850-3 display controller.
