Power Integrations today announced its LYTSwitch™-7 single-stage, non-isolated, TRIAC-dimmable, buck topology LED driver IC family. Capable of delivering up to 22 watts without a heatsink in a very small SO-8 footprint, these high-efficiency devices are suitable for bulbs, tubes and fixtures. LYTSwitch-7 designs do not require bleeders; employing simple, passive damping for TRIAC management and an off-the-shelf, single-winding inductor, reducing component count to just 20, as compared to approximately 35 parts for typical dimmable LED driver boards.
Design Example Report (DER-531) from PI uses InnoSwitch-EP 900V rated, the industry's first AC/DC IC with isolated, safety rated integrated feedback. This new design demonstrates auxiliary power supply for industrial application with high power density and very high efficiency.
PI recently released a new design (DER-471) using InnoSwitch-CE, the latest of PI's InnoSwitch family of ICs. This 15 W design for adapter applications features all the benefits of secondary side control with the simplicity of primary side regulation.
