BA9755S Datasheet High Voltage Controller For Crt Displays

Manufacturer: ROHM

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