BA9755S High voltage controller for CRT displays

Pin No. 1 Pin name GND Function Ground This is the common ground for the small signal system and the power system, and so requires a stable ground suitable for common impedance. PWM wave output Output is fixed at the low level when the protector circuit or thermal shutdown circuit is activated. Pow.

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 components include an output voltage error detector and an overcurrent det.
