LED-based bulbs that replace their incandescent counterparts require a significant amount of engineering (Fig. 1). In the 60 W range the LED driver board can take up about 15% of the overall cost of ...
Supertex’s PS30 constant-frequency (67 kHz), constant duty-cycle LED driver provides high power factor correction (PFC) for dimmable off-line LED bulb and tube applications. The device is intended to ...
The TPS92075 is designed for phase-dimmable, offline AC/DC LED lamp and downlight applications. Offered in a very small 6-pin TSOT package, it achieves power factor correction above 0.9 while ...
Driving LEDs, especially high-brightness, higher-power ones, is simple in concept – all you need is a dc/dc converter that can supply the necessary power, at the required current level, typically in ...
