PI introduced for the introduction of LED lighting lamp T8 ballast reference designs

LinkSwitch-PH LED Driver IC to meet the PF and THD specifications, efficiency of 91%; specifically designed for commercial and industrial lighting

San Jose, California, USA, August 24, 2011 (Reuters) - for general lighting of the LED driver IC, a leader in the field of Power Integrations, Inc. (NASDAQ: POWI) today announced the release of a new 25 W LED T8 tube Ballast Power supply reference design. The design (DER-287) The most striking is that over 91% efficiency, achieve industry-leading level, while the power factor (PF greater than 0.9) and harmonic distortion (EN61000-3-2 Class C) in meet commercial requirements. DER-287 is used Link Switch-PH Series LED driver IC designed for single-stage one LNK409EG converter. Single-stage technology by eliminating the conventional two-stage design used in lightI solator And large aluminum electrolytic capacitors can be significantly extended product life.

Power Integrations, product marketing manager Andrew Smith said: "In light of the overall increase lighting efficiency and achieve high power conversion efficiency and LED options are equally important, if not a single-stage topology, in the narrow space of the T8 lamps a cost-effective way to make more than 88% efficiency is extremely difficult to do, while the efficiency of this design is easily more than 91%. "Smith added:" Most areas require commercial and industrial lighting products must have low THD or high-PF - LinkSwitch-PH LED driver IC can easily meet this specification, so that the final design for the global market. For more information see the report of this new design paradigm. "

In addition to using the controller, drives and switching MOSFET also integrated into a single package within a highly integrated single-chip design outside, Power Integrations' Link Switch-PH product line also includes thermal protection and overcurrent protection with the many protection features including. This means that only requires minimal external components to achieve the design - This compact space of the T8 lamp is extremely important.
