LED drivers offer flicker-free TRIAC dimming

LED drivers offer flicker-free TRIAC dimming

Optimized for isolated designs and rated up to 50 W output power, the LinkSwitch-PH and LinkSwitch-PL LED driver ICs deliver flicker-free monotonic TRIAC dimming. These monolithic devices feature integrated single-stage power factor correction (PFC), enabling SSL luminaires to achieve PF > 0.9.

The LinkSwitch-PH incorporate primary-side-control technology, which eliminates the optocoupler and supporting components used in traditional isolated flyback designs, while the non-isolated LinkSwitch-PL designs further reduce component count, resulting in improved reliability and a BOM. Operating at input voltages up to 305 Vac, the parts incorporate the controller and MOSFET onto a single silicon die. These ICs meet or exceed all regulatory standards, such as Energy Star and EN61000-3-2. (From $1.18 ea/10,000 — contact company for availability.)
