Application
The backlight system consists of light-emitting components, light guide plates and backlight power supplies. The power of TV backlight power supplies is generally 100-500W, which mainly converts the AC voltage of the mains into a 12V DC voltage output to supply power to the display. Since there is also a DC-DC voltage converter on the motherboard inside the display to obtain 8V/5V/3.3V/2.5V voltage, the 12V DC voltage output by the power supply can meet the working requirements of the display. The electrical structure used in the TV power supply adopts PFC, LLC, SR, Falyback, BOOST+CC/CV topology, etc. Inmark provide high-voltage and low-voltage MOSFETs with good EMI and excellent thermal performance, providing good performance for the miniaturization and thinness of the backlight power supply.
