LA7836 Details

Overview The LA7836 is an IC that contains the vertical deflection output circuit with a driver for color, B/W TV sets, monitors, and display units with a large aperture (maximum deflection current 2.2Ap-p) and is placed in an SIP13H package. The LA7836 features fewer external parts and low power dissipation. Since both DC feedback and AC feedback can be provided inside the IC, it is easy to design the vertical deflection circuit. The LA7836 can be used in conjunction with single-chip IC LA7650 series (NTSC), LA7680 series (PAL/NTSC) (VIF, SIF, video, chroma, and deflection circuit) to provide all the functions required for color TV signal processing.Features • Low power dissipation because of on-chip pump-up circuit. • On-chip 50/60Hz vertical amplitude control circuit. • On-chip ramp generator. • On-chip driver circuit. • Vertical output circuit. • On-chip thermal protection circuit. • Minimum number of external parts required.

FAQs

What is LA7836?

The LA7836 is a vertical output (deflection) circuit IC designed for use in CRT (cathode-ray tube) televisions. It is commonly used to drive the deflection yoke for the vertical deflection of the scanning beam in CRT displays.

How Does LA7836 Work?

The LA7836 works by amplifying and processing the vertical deflection signal from the TV's signal processing circuitry and driving the deflection yoke coil to move the scanning beam vertically across the CRT screen. It also includes various protection and control features to ensure reliable and stable operation of the CRT display.

How Many Pins does LA7836 have and What are the Functions of the Pinout Configuration?

The LA7836 is housed in a 7-pin SIP (Single In-line Package) configuration. The pinout configuration includes:

  • VCC: Power supply pin.
  • VERT OUT: Vertical output pin connected to the deflection yoke coil.
  • S-COR: Sawtooth wave correction input pin.
  • YK: Ground pin for the deflection yoke.
  • F-COR: Flyback sawtooth wave correction input pin.
  • GROUND: Ground pin.
  • COL: Collector pin of the internal vertical output power transistor.

What are the Pros and Cons of LA7836?

Pros:

  • Suitable for CRT Displays: Specifically designed for driving the vertical deflection yoke in CRT televisions.
  • Integrated Protection Features: Includes built-in circuitry for overcurrent protection and thermal shutdown.
  • Compact Package: The 7-pin SIP package is space-efficient and easy to handle.
  • Cost-Effective Solution: Provides a cost-effective solution for vertical deflection in CRT displays.

Cons:

  • Obsolete Technology: Due to the decline of CRT displays, availability of the LA7836 IC may be limited.
  • Specialized Application: Limited use for CRT display applications, may not be suitable for modern display technologies.

Are There Any Equivalents/Alternatives to LA7836 for Recommendation?

Equivalents to LA7836 include the LA7837 and LA7838, which are similar vertical output ICs designed for CRT displays.
