High-voltage control circuit for CRT  
displays  
BA9756FS  
The BA9756FS is LSIs that control CRT anode voltage in multi-scan monitors and similar devices, using  
a chopper-type voltage control circuit. The internal sawtooth wave generator circuit uses automatic gain control  
(AGC) to enable coverage of a wide range from 30kHz to over 150kHz. The BA9756FS is equipped with an internal  
high-precision voltage source featuring an output voltage precision of ± 0.7%.
