New isolated LED controller with active power factor correction (PFC) is specifically designed for driving LEDs from a universal input range of 90VAC to 265 VAC. The LT3799 is cost efficient and more reliable because it delivers a well-regulated current to the secondary side without using an opto-coupler, and it is also compatible with standard TRIAC in-wall dimmers.

Opto-electronic Transceiver Modules, a System Design Perspective
Introduction Small Form Factor (SFF) optical transceiver packages for use at 1-2 Gbits/s data rates have been described by several authors [1-5]. These rely on dual miniature optical connectors such as the MT-RJ or the LC to provide optical-component case widths as small as one centimeter. Passive alignment of the optical fibers with the active optical devices is achieved with … [Read more...]
