New off-line LED driver IC from Infineon for lighting apps

Infineon has introduced the ICL8001G, a new off-line driver IC for high-efficiency LED bulbs with dimming for residential lighting.

The key features of the ICL8001G off-line driver IC are,

Single stage, primary control with PFC and dimming function
Isolated driver output for efficient thermal management
Phase-cut dimming supporting trailing and leading-edge dimmers
Minimized external components enable small form factor and maximum reliability
High power and light quality
Multiple safety functions for full system protection in failure situations
Supports 40W/60W/100W incandescent bulb replacement and all consumer lighting applications
Up to 90 percent efficiency
Digital soft-start and an integrated Start-Up cell for instant on
Cycle by cycle current limitation
Short circuit, over voltage protection and over temperature detection

Infineon says that driver boards based on the ICL8001G implement an primary control technique to manage the power consumption of LEDs. Using 25 components for a 10W LED (60W equivalent) lamp, which is a 50 percent reduction compared to alternatives and a cost reduction of approximately 30 percent, the printed circuit board area of the reference design is just 20mm x 70mm. At that size the PCB can easily be embedded within the common screw-in form factor of a lamp bulb. All components are assembled on a single-sided PCB, contributing to further cost reduction.

"There is a wide acceptance of the efficiency advantages of LED lighting," said Sandro Cerato, Vice President & General Manager, ASIC & Power IC at Infineon Technologies. "With the ICL8001G Infineon offers innovation for lighting applications as it significantly reduces costs while improving the performance of the system, thereby helping use of available electricity in a more efficient manner."
