# BP2866C (Component) ## Description The BP2866C, manufactured by 晶丰明源半导体, is a high precision buck constant current LED driver designed for universal input offline LED lighting applications. Operating in critical conduction mode, this component is suitable for 85Vac~265Vac input and integrates a 500V power MOSFET. It features patented demagnetization detection technology and high-voltage JFET power supply technology, eliminating the need for a VCC capacitor and starting resistors, thereby minimizing system cost and size. The BP2866C offers precise output current and excellent line regulation through a patent-pending current control method. It includes robust protection functions such as LED short circuit protection, VCC under voltage protection, and thermal regulation. Available in a SOP7 package, it ensures a +5% LED output current accuracy and is ideal for applications like LED candle lights and bulbs. ## Component Details - **Owner:** vasy_skral - **Created:** 4/1/2025 - **Last Updated:** 4/1/2025 - **Visibility:** Public - **Datasheet URL:** https://cdn2.flux.ai/copilot-datasheets/pdf-upload-ecf2dc33a169ee81df6518d18822d9dd800752bb024c7f203ee191cb00319963/c15bc623a71c5159678b531e924c3f18f55c641dcdd5cc1fee3507b1ae3ce3b8.pdf?GoogleAccessId=graviton-mvp%40appspot.gserviceaccount.com&Expires=4897097565&Signature=vrY%2FimdEFMMdbCm8HqrrBLHo0tM9GmgCQE%2BEZ0i3VlkLQfC8aEkEDnkEHy%2B5OaEEkRjBT9U95g%2BvCvJOvpfVsKX7RQ%2BFnxYO0134ZXQDTjS0Vdr4i%2FzrnnO6YIpS3OfrmfwklWt7Z%2F4oebQZdG%2Bweh0HKw%2B6sE5APYPBFlaty6ligdXc9z5nPeFSCnDzIgclLSmNT11Od42pslrNCpURt%2B983DLiIOsmJAmjc7HMiweoPPIjQimfxcGHdNLlt1Z74UctSXS1H2Ez%2BhheUDwKrl%2BW8IJtTbldMsu57yp%2BsMiDbm9%2BGBuFrbwrpXG87CVe9KAJbh3yy1DGiDcybb%2B3XQ%3D%3D - **Part Type:** Integrated Circuit - **Manufacturer Part Number:** BP2866C - **License:** https://creativecommons.org/licenses/by/4.0/ - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Name:** BPS Electronic - **Used in:** 1 project - **Part Type:** Integrated Circuits - **Sub-Type:** Logic - **MPN:** BP2866C - **Pin Count:** 7 - **Logic Function:** AND ## Pins | Pin | Name | Type | |-----|------|------| | 1 | GND | | | 2 | NC | | | 3 | NC | | | 4 | HV | | | 5 | DRAIN | | | 6 | DRAIN | | | 8 | CS | | --- *Generated from [https://www.flux.ai/vasy_skral/bp2866c~z2y](https://www.flux.ai/vasy_skral/bp2866c~z2y)*
