Creating more reliable and cost-effective LED lighting applications

Microchip Technology now offering a next-generation sequential linear LED driver for offline lighting applications. The CL88020, an extension of the company’s CL88XX family, is designed to drive a long string of low-cost LEDs directly from the 120VAC line input. The product allows customers to create reliable, cost-effective and compact LED lighting applications by having high 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 device was designed to minimize driver circuit component count to allow for a very small and efficient design. The simple design allows for a single-layered PCB design. Unlike the conventional AC/DC switch mode power supply, the basic driver circuit consists of the IC, two small ceramic capacitors and a bridge rectifier only. High-voltage capacitors, transformer or inductors, EMI filters or PFC circuitry are not required. This allows for a smaller solution size and a lower overall BOM cost as compared to traditional LED solutions. “The approach of AC to direct drive helps our customers address many concerns related to their designs,” continued Pazul. “This latest LED driver enables customers to design simpler, smaller and more robust high-performance LED lighting systems than previously possible.”
