Cirrus Logic announced the CS161X LED driver IC with a claim of near 100% dimmer compatibility while Linear Technology announces a new buck-boost SSL driver IC, and Power Integrations offers a 100W-retrofit, A-lamp reference design.
Cirrus Logic is a newcomer to the LED driver IC market, but the company claims it will make an immediate impact asserting that a tier-1 lighting vendor will shortly ship a high-volume, retrofit-lamp product based on the new CS161X IC. The company says that it has tested the 2-stage CS161X solid-state lighting (SSL) driver IC with more than 200 triac dimmers and that the IC delivers smooth, flicker-free dimming down to below 2% of maximum output current.
Cirrus has taken a similar path to Marvell and iWatt in recently-launched dimmers |
