Description:

• No auxiliary winding is required to power the IC
• No high-voltage start up depletion MOSFET is required, fast time to light can be achieved inherently with cascode topology
• No start up resistor is required that would cause significant losses during the entire operation. These losses can be eliminated by using the cascode topology which increases the system efficiency and lifetime.

Summary of Features:

• Cascode topology enables lower system cost and higher system efficiency
• Supports wide range AC or DC input
• Power Factor > 90%, THD < 20%
• Line/load regulation capabilities ±5%
• LED output current up to 500mA

Benefits:

• Minimum external components supporting small form factors and easy design-in
• IC concept supports single inductors without aux winding
• Advanced cascode topology eliminating the need for a HV cell at the universal input from 90-305 V AC
• Full set of protection modes including intelligent Over-Temperature Protection

Target Applications:

• T8 lamp
• GU10 lamp
• A-lamp
• Downlights
