APPLICATION NOTE 1748
VFD Grid/Anode Supply Using MAX6850-MAX6853 PUMP Output

Abstract: 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.

This application note discusses how to use the MAX6850, MAX6851, MAX6852, and MAX6853 vacuum fluorescent
display (VFD) controllers' PUMP clock output to build a minim
