Description

The LA78040 is a vertical deflection output IC for high image quality TV and CRT displays that supports the use of a bus control system signal-processing IC. The sawtooth waveform from the bus control system signal-processing IC can directly drive the deflection yoke (including the DC component). Color TV vertical deflection system adjustment functions can be controlled over a bus system by connecting the LA78040 to a Sanyo LA768X series or LA769XX series bus control system signal-processing IC.

Key Architecture

  • Vertical deflection power amplifier
  • Direct yoke drive capability (including DC component)
  • Integrated pump-up (bootstrap) circuit
  • Thermal protection included

Core Features

  • Built-in pump-up circuit → improves output swing and efficiency
  • Capable of directly driving vertical deflection yoke
  • Compatible with bus-controlled video processors (e.g., LA76931)
  • Thermal shutdown protection for reliability
  • Supports high-quality CRT image performance

Design Notes (Critical Points)

  • Heat sink is mandatory due to power dissipation
  • Pump-up capacitor value affects vertical amplitude
  • Ensure proper grounding to avoid vertical jitter
  • Yoke impedance must match IC capability
  • Thermal protection should not be triggered in normal operation

Advantages

  • High integration → fewer external components
  • Stable and precise vertical deflection
  • Compatible with digital bus-controlled systems
  • Built-in protection improves reliability

Typical Applications

  • CRT televisions
  • CRT monitors
  • Video display systems using analog deflection

Related / Compatible ICs
