San Jose, Calif., December 16, 2014 – Power IntegraTIons, Inc. (Nasdaq: POWI), a leader in high-efficiency, high-reliability Led Driver ICs, today introduced an LED street light, high bay light And new reference designs for other high power LED lighting applications. The new reference design, the RDR-382, features a constant current, 43 V (nominal), 150 W reference Power Supply designed using Power IntegraTIons' HiperPFSTM-2 PFC controller IC and HiperLCSTM integrated LLC power stage IC.
Traditional dual-stage drivers use separate PFC and LLC stages, requiring multiple DC-DC converters to convert the output to constant current (CC) when generating a constant voltage (CV) output. In contrast, the RDR-382 uses an innovative feedback and control scheme that enables the LLC to provide constant current directly at the output. As a result, the number of components is reduced by about one-third, the efficiency is increased to over 93%, and the power supply size is greatly reduced after the DC-DC converter is omitted. In addition, the high-rated LLC switching frequency (250 kHz) reduces the size of the core components required, while the continuous conduction mode variable-frequency PFC stage reduces EMI interference compared to fixed-frequency solutions.
Andrew Smith, senior product marketing manager at Power IntegraTIons, said: "Reliability is especially important for high-power lighting applications with output powers above 75 W. Because of the high-efficiency design of this design, the heat generated is small, and the number of components is small. And therefore have a long service life."
