Silicon Success Stories

Make your LEDs last twice as long for less money and in less space!
iSine's S006 LED ASIC driver can double the typical lifetimes of LED lamps from 5 to 10 years by eliminating the bulky power supply unit in the luminaire. Bypassing the AC to DC conversion improves efficiency and the power factor. Fewer parts means lower costs and a smaller, thinner and lighter unit.
