Key features

• •Voltage Conversion and Output: The core function of the TV power board is to convert the input AC power into a variety of stable DC voltages to meet the needs of different components inside the TV
• •Power board structure and functional unit: The structure of the power board varies according to the power of the TV and the type of screen, and the common functional units include secondary power supply, main power supply, PFC (power factor correction) circuit, background light source drive circuit, etc
• •Boot timing control: The output voltage sequence of the power strip needs to match the boot sequence of the TV. Normally, when the machine is turned on, the +5V standby voltage is output first, the CPU control system is started, and then other voltages are output in turn according to the instructions
• •Thermal and Reliability Design: Power strips generate heat during operation, so thermal design is crucial. Common thermal measures include setting up heat sinks, optimizing component layouts, and employing low-impedance components
• •Protection Function: The power strip has a variety of protection functions, such as overload protection, overtemperature protection and overvoltage protection. These protection functions can effectively prevent damage to the power strip under abnormal conditions and prolong its service life
