Texas Instruments UCC28811 | Demoboard UCC28810EVM-003

Description

This converter was designed to support up to four strings of 15 high brightness LED’s in series (58.5 Vmax per string). The converter will provide 500-mA average current to each string. The designincorporates an interface for microprocessor control to allow for shutdown into a low power mode (<0.5 W)and PWM dimming of the LED’s.

Features

• 90-VRMS to 265-VRMS Operation
• Boost Follower or Fixed Output PFC Stage
• PFC Disable
• Output Current Disable
• External or Internal PWM Dimming
• Output Isolated from Line Input
• Open Circuit Protection (If one LED string fails open the remaining strings stay on.)

Typical applications

• AC Input General Lighting Applications Using HB LEDs
• Outdoor Lighting: Street, Roadway, Parking, Construction and Ornamental LED Lighting Fixtures Lighting
