Sequential Linear LED Driver
Description
CL88030/31
Sequential Linear LED Driver with Four or Six Taps
Features
• Suitable for 120VAC/230VAC/277VAC Nominal Input Voltage - ± 15% input voltage tolerance recommended
• Targeted for 2W and Greater Output Power • Programmable Overtemperature Protection
- Provides gradual reduction in light output with increasing temperature
• Active Line Regulation - Provides fairly constant output power over variations in AC line voltage - Adjustable “knee” of regulation
• 4 Taps(CL88030) or 6 Taps(CL88031) with Two Current Set Resistors - Allows optimization of THD
• Optional Reduced Flicker Index - Provides near-continuous power to the LEDs - Reduces strobing - Uses an external capacitor
• Compatible with Phase-cut Dimming, both Leading-edge and Trailing-edge
• Uses a Thermally Enhanced DFN-10 Package with Bottom Heatslug - No high voltage Pins - Shunt regulator input - Power dissipation is in the external FETs and LEDs, not in the IC
Applications
• LED lamps • LED lig...
