Description

The ICL8001G employs quasi-resonant operation 

mode optimized for off-line LED lighting, especially 

dimmable LED bulbs for incandescent lamp 

replacement. 

Precise PWM generation enables primary control for 

phase cut dimming and high power factor PF>98%. 

Significant improved driver efficiency, up to 90%, 

compared to other conventional solutions. Tthe 

product has a wide operation range (up to 26V) of IC 

voltage supply and lower power consumption. Multiple 

safety functions ensure a full system protection in 

failure situations.

With its full feature set and simple application, the 

ICL8001G represents an outstanding choice for quasiresonant flyback LED bulb designs combining feature 

set and performance at minimum BOM cost.
