CL88020T-E/SE

The CL88020 LED Driver Integrated Circuit (IC) is an off-line sequential linear LED driver designed to provide 8.5W of LED power from a 120 VAC nominal input voltage. CL88020 is designed to drive a long string of inexpensive, low-current LEDs directly from the AC mains. No capacitors, EMI filters, or power factor correction circuits are needed unless the optional reduced light output ripple feature is desired. High efficiency is achieved by shutting off upstream regulators when downstream regulators achieve regulation. This makes controlling overall input current easier than trying to control multiple current paths, thereby tracking the input sine wave voltage.

• Optimized for 120VAC nominal input voltage
• Targeted for 8.5W output power
• Programmable overtemperature protection
