LCD TV
Power integrations provides power solutions for all LCD TV standby power supplies, and the main power supply for LCD LIPS applications. Reference designs are available for the standby and standby/auxiliary output power supplies for SUPERLIPS applications. PI also offers solutions for LCD TV LED backlighting.
Available solutions for different architectures are shown in figures 1-3 (below). A number of reference designs for LCD TV standby power supplies are also available.
