PI Unveils Design: 18 W A19 LED Lamps to Replace 100 W Incandescents
Power Integrations today announced DER-323, a reference design for an 18W, 88%-efficient, non-isolated A19 LED driver based on LNK460VG, a low-profile IC from the company's LinkSwitch™-PL family. The design is suitable for a 100 W incandescent bulb replacement and is optimized for low-line (90 VAC to 135 VAC) operation. The circuit is low-cost, requiring only a simple single-sided board and 25 components. No potting is necessary and the transformer is replaced by a low-cost inductor.
