Abstract:
A horizontal drive circuit employed in CRT displays which uses a switch-mode power supply operating in a boost topology to generate the appropriate supply voltage needed by the horizontal drive circuit is provided. The boost power supply is integrated into the horizontal drive circuit which allows for low printed circuit board area, low cost, and good performance over many different horizontal frequencies.
