Reference Design Reduces Energy Waste

With the release of the new of DAK-33, Power Integrations Inc. has taken another step in enabling switching power supplies to meet all current and proposed governmental energy efficiency regulations. The DAK-33 is a new design accelerator kit for LCD monitor and tv applications. The DAK-33 provides a reference design to both dramatically reduce energy waste and speed design time for ac-dc flyback power supplies using the company’s EcoSmart technology and its highly integrated TOPSwitch®-GX high-voltage power conversion ICs.

The DAK-33 was created specifically to meet LCD monitor and LCD television power requirements. The kit contains a tested energy-efficient 45W power supply adapter, PI Expert™ design software, TOPSwitch-GX samples, and extensive design collateral. In standby mode, the 12V, 3.75A adapter draws less than one watt of input power at 230Vac while supplying 0.5W to its load. The design operates over a wide input voltage range (90Vac to 265Vac) with greater than 83% efficiency at full power.
