Offline LED Controller For PFC And Dimming With Integrated 800 V CoolMOS®

The ICLS8082G employs a quasi-resonant operation mode optimized for off-line LED lighting, especially for dimmable LED bulbs for replacement of incandescent lamps.

Precise PWM generation enables primary control for phase-cut dimming and high power factors (PF) > 98 %. It offers significantly improved driver efficiency, up to 90 %, compared to other conventional solutions. The product has a wide operation range (up to 26 V) of IC voltage supply and lower power consumption. Multiple safety functions ensure full system protection in failure situations.

With its full feature set and simple application, the ICLS8082G represents an outstanding choice for quasiresonant flyback LED bulb designs combining the feature set and performance at minimum BOM cost.

ICLS8082G產品亮點:

• Quasi-resonant control for highly efficient LED driving solutions

• Primary-side flyback control with integrated PFC and phase-cut dimming

• High-voltage CoolMOS® and startup cell for short "time to light"

• Best-in-class system BOM for dimmable LED bulbs with the integrated CoolMOS®

• Miniatuarization with the integrated CoolMOS®

ICLS8082G主要特性:

• High, stable efficiency over a wide operating range

• Optimized for trailing- and leading-edge dimmers

• Precise PWM for primary PFC and dimming control

• Startup cell for Vcc precharging with constant current

• Built-in digital soft start

• Foldback correction and cycle-by-cycle peak current limitation

• VCC over/undervoltage lockout

• Auto restart mode for short-circuit protection

• Adjustable latch-off mode for output overvoltage protection

ICLS8082G應用:

100W / 60W / 40W incandescent bulb replacement

Lamp retrofits, LED tubes / luminaires, downlights ? ?

評估板EVAL-LED-ICLS8082G-B2主要特性:

• Quasi-Resonant operation for efficient LED Controller

• Integrated Controller and High Voltage CoolMOS® and start-up Cell

• Miniaturization Possible with the integrated CoolMOS®

• Improved THD < 20 % at typical value of 230V

• Secondary and primary side control feasible

• Energy efficient phase cut dimming

• Precise PWM for PFC and primary side 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

• Auto restart mode for output overvoltage protection

• Auto restart mode for short circuit protection

• Snubber Circuit to limit the voltage spikes caused by the transformer leakge inductance to safe value.This limits the avalanche losses of CoolMOS® transistor.
