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.

Features
• High, stable efficiency over wide operating range
• Optimized for trailing- and leading-edge dimmer
• Precise PWM for primary PFC and dimming control
• Power cell for Vcc pre-charging with constant current
• Built-in digital soft-start
• Foldback correction and cycle-by-cycle peak current limitation
• VCC over/ under-voltage lockout
• Auto restart mode for short circuit protection
• Adjustable latch-off mode for output overvoltage protection
