Direct-AC-drive Chip Makes LED Lighting Affordable


Microchip has unveiled an off-line sequential linear LED driver designed to provide 8.5W of LED power from a 120 VAC nominal input voltage. The CL88020 is designed to drive a long string of inexpensive, low-current LEDs directly from the AC mains.

The product helps create reliable, cost-effective and compact LED lighting applications by having High Power Factor (PF) without the need for switch-mode power conversion which is typically required for LED lighting design.

“The transition from traditional lighting to LED is here and moving at a fast pace,” said Keith Pazul, director of marketing for Microchip’s Analog, Power and Interface Division. “Microchip has a rich and diverse LED lighting portfolio, and customers are continually seeking better electronic solutions such as those found in this new device.”

The CL88020, according to Microchip, minimizes driver circuit component count to allow for a single-layered Printed Circuit Board (PCB) design.


“Unlike the conventional AC-DC switch mode power supply, the basic driver circuit consists of the CL88020 IC, two small ceramic capacitors and a bridge rectifier only. High-voltage capacitors, transformer or inductors, electromagnetic interference (EMI) filters or Power Factor Correction (PFC) circuitry are not required. This allows for a smaller solution size and a lower overall bill of material (BOM) cost as compared to traditional LED solutions”, the firm added.
