... Few External Components Protection against Low V Description Designed for TV and monitor applications, the STV9380A is a Class-D vertical deflection booster assembled in a 20-pin plastic DIP package. It operates with supplies up to ±18 V and provides an output current up to 2.5 A The internal flyback generator avoids the need for an extra power supply ...

... Functional Description The STV9380A is a vertical deflection circuit operating in Class D. Class modulation method where the output transistors work in switching mode at high frequency. The output signal is restored by filtering the output square wave with an external LC filter. The major interest of this IC is the comparatively low power dissipation in regards to traditional amplifiers operating in class AB, eliminating the need of an heatsink ...
