Power Integrations (San Jose, CA) announced four reference designs describing drivers for dimmable PAR 30 and PAR 38 LED light bulbs. Jointly developed by Power Integrations and CREE, the designs showcase the combination of Power Integrations’ LYTSwitch-4 driver ICs and CREE MT-G2 EasyWhite LEDs. DER-364 and DER-365 detail low- and high-line PAR 30 LED bulb drivers, respectively, while DER-350 and DER-396 address low- and high-line PAR 38 bulbs. Features include:
- EN61000-3-2C regulations for total harmonic distortion (THD).
- Less than 10% THD.
- Regulation of better than +/- 5% across load and production spread.
- Start-up of typically less than 500 milliseconds even when dimmed to less than 10% light output.
