Including New Design Ideas and Engineering Reports

One of the areas that the Energy Using Products Directive (EuP) EU will effect across different industry product groups will be power supplies. Group 6 of the directive addresses standby and off-mode losses of electrically powered devices. Here's a broad range of design support materials for power supply designs featuring Power Integrations' ICs.

• TOPSwitch-HX
  • Power Supply for LCD Monitors
    Use these design support materials for your power supply designs for LCD monitors and TVs. They feature TOP258PN in a 35 W power supply.
    • Reference Design Kit 142, providing the essential materials to get started on your LCD power supply design, including samples and a fully functional reference board
    • Reference Design Report 142, containing the power supply specification, schematic, bill of materials, transformer documentation, printed circuit layout, and performance data for this design
    • Design Idea 142, the design idea for this power supply
  • Power Supply for Set-Top Boxes
    This design idea uses TOP257P for a 30 W output design intended for an external adapter for set top-box power supplies, which typically require low standby and no-load power consumption.
