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.
