Frequently Asked Questions
What is the primary application of the UCC28811DG4?
The UCC28811DG4 is designed for offline LED lighting power supply applications, where it acts as the primary power controller in an LED driver circuit operating from a rectified AC mains input. It targets LED bulbs, LED tubes, and LED panel light fixtures requiring efficient constant-current LED drive.
What does primary-side regulation mean in the context of the UCC28811DG4?
Primary-side regulation means the UCC28811DG4 controls the LED current and output voltage by sensing parameters on the transformer primary side, eliminating the need for a secondary-side feedback network using an optocoupler and shunt reference. This reduces component count and cost in the LED driver design.
What package does the UCC28811DG4 come in?
The UCC28811DG4 is housed in an 8-Pin SOIC (Small Outline Integrated Circuit) package with JESD-30 code R-PDSO-G8 and plastic/epoxy body material. This standard surface-mount package supports automated assembly and is suitable for compact LED driver PCB layouts in mass-production lighting products.
Is the UCC28811DG4 suitable for isolated LED driver designs?
Yes, the UCC28811DG4 is compatible with isolated flyback converter topologies commonly used in offline LED drivers. Its primary-side regulation approach works with an auxiliary winding to sense output conditions, providing isolation between the AC mains input and the LED load output without direct electrical connection.
What is the JESD-609 Code e4 on the UCC28811DG4?
JESD-609 Code e4 indicates the UCC28811DG4 is a lead-free (Pb-free) device soldered with SAC (tin-silver-copper) compatible solder alloys. This designation confirms RoHS compliance and suitability for use in lead-free manufacturing processes required by European and global environmental directives.
