Solomon Systech Launches Offline LED driver ICs SSD1072/1073

With built-in active power factor correction feature, the power factor of Solomon Systech’s SSD1072/1073 can reach up to 0.98. Active power factor correction eliminates a large electrolytic or tantalum filter capacitor after the input bridge rectifier, which not only helps enhance system lifetime, which is always dominated by the capacitors, but also reduces the component count and thus lowers the production cost.

System power efficiency is always a key distinguishing feature for LED drivers. With SSD1072/1073, the system power efficiency can be improved to up to 92%. Moreover, as output current is controlled by external MOSFET, it is adjustable by external circuit for different applications like LED bulb (E27 / GU10 / G24 / PAR) and LED tube light.

SSD1073 also has dimming function that allows extra energy saving. Knowing that not all users have dimmers installed to adjust light levels, the On/Off dimming technology of SSD1073 offers an alternative solution for the energy efficiency retrofit market. With SSD1073, dimming can be done simply by using traditional wall switch, allowing toggling off and on within just 1 second.　

In addition, several safety features, including natural current-limited soft start, over-temperature protection, open load protection, open feedback loop protection, are also embedded in SSD1072/73 to enhance competitiveness.

“As power saving has become increasingly important for the lighting market, LED lighting driver ICs enjoy great market potentials. Our newly launched innovative products, SSD1072/73, given their many energy saving features, offer a cost effective solution for the surging LED application market,” said Mr. WM Lo, Vice President, Business Operations of Solomon Systech Limited.
