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 precision of ±1%. Using a high-precision voltage detection resistor makes it possible to set anode voltage without adjustment. Other internal components include an output voltage error detector and an overcurrent detector, which detects overcurrent when the power is turned on.
