High voltage controller for CRT

displays

BA9755S

The BA9755S is an LSI chip with a chopper voltage controller designed to control the anode voltage of multiscan

monitors and other CRTs. There are two internal high-precision power supplies, each with an output voltage preci-

sion of ±1%. Using a high-precision voltage detection resistor makes it possible to set anode voltage without adjust-

ment. Other internal components include an output voltage error detector and an overcurrent detector, which detects

overcurrent when the power is turned on.

Applications

•

CRT displays and HDTV products

Features

•

1) Internal chopper voltage controller.

3) Internal output voltage error detector.

4) Internal buffer circuit that directly drives power MOS-

FET for output drive.

2) Two internal high-precision power supplies, each

with an output voltage precision of ±1%.
