TSUMV59XU-Z1 Datasheet – LCD Driver Chipset ( PDF )

Posted on by pinout

The TSUMV59XU-Z1 is an all-in-one LCD controller chipset. It serves as the heart of many small to medium-sized LCD TV mainboards, especially in aftermarket repair boards and low-cost display products. Instead of requiring multiple ICs for video decoding, scaling, and driving, this device combines these tasks into a single package, simplifying board design. Taiwan N threaded head, Universal TV driver board HDMI interface with USB port.

Description

The TSUMV59XU is  LCD Universal Universal TV board Chipset.

The new high-definition programs, U disk upgrade program, very easy to use, supports 8.9-inch -42 inch screen, the maximum support resolution: 1920 – 1080.

Features

1. Integrated Scaler Engine:

Supports input resolutions up to Full HD (1920×1080) and provides downscaling or upscaling to match the panel’s native resolution.

2. Multiple Video Input Interfaces:

Equipped with HDMI, VGA, CVBS (AV), and sometimes USB media playback support depending on the board implementation. This makes it suitable for a variety of consumer display products.

3. Built-in Audio Processing:

Includes audio DAC support and onboard amplifier compatibility for driving basic speaker outputs, eliminating the need for separate audio ICs.

B778 pnp transistor

Description

The B778 (commonly referenced as 2SB778) is a PNP planar silicon power transistor designed for audio amplification and power conversion applications. It is typically used as the complementary pair to NPN transistors like 2SD998 or similar devices in push-pull amplifier configurations.

This device is optimized for high current handling and power dissipation, making it suitable for medium-to-high power analog and switching circuits.

1. High Current Capability

2. High Power Dissipation

Absolute Maximum Ratings

1. Collector-Base Voltage: Vcbo= – 120 V

2. Collector-Emitter Voltage: Vceo = – 120 V

3. Emitter-Base voltage : Vebo = – 6 V

4. Collector Current (DC) : Ic = – 10 A

5.Collector Dissipation : Pc = 80 W

6. Junction Temperature: Tj = 150°C

Design Notes (Critical Points)

  • Heat sink is mandatory for high-power operation
  • Use emitter resistors (~0.22Ω) for current balancing
  • Ensure proper bias network to avoid crossover distortion
  • Protect against overcurrent and thermal overload
  • Maintain safe operating area (SOA) in linear mode

Typical Applications

  • Audio power amplifier output stages
  • Hi-Fi stereo systems
  • DC-DC converter circuits (linear or low-frequency switching)
  • High-current driver stages
  • Power regulation circuits

Alternative / Equivalent Products

  • 2SB817
  • 2SA1941 (higher performance audio pair)
  • TIP2955
  • MJL1302A (high-end audio PNP)
