BP2861XJ is a high precision Buck constant current LED driver. The device operates in critical conduction mode and is suitable for85Vac~265Vacuniversal input offline LED lighting.
The BP2861XJ integrates a 500V power MOSFET, with gate MOSFET driving technique. It does not need Vcc capacitor and startup resistor. It can achieve excellent constant current performance with very few external components, so the system cost and size are greatly reduced.
BP2861XJ operates in critical conduction mode, it can achieve precise output current and excellent line regulation. The driver output current does not change with the inductance and output voltage.
The BP2861XJ offers protections to improve the system reliability, including LED short circuit protection, and thermal regulation function.
