Overview
The LA78040B is a vertical deflection output IC for TVs and CRT displays with excellent image quality that use a BUS control system signal processing IC. This IC can drive the direct (even including a DC component) deflection yoke with the saw tooth wave output from the BUS control system signal processing IC.
Functions:
- Low power dissipation due to built-in pump-up circuit
- Vertical output circuit
- Thermal protection circuit built in
- Excellent crossover characteristics
- DC coupling possible
Specifications:
- Maximum Ratings at Ta = 25°C
- Pump-up block supply voltage: 34V
- Output block supply voltage: 70V
- Allowable power dissipation: 9W
- Operating temperature: -20 t0 +85°C
