BP2886F

Overview
The BP2886X is a high-precision step-down LED constant current driver chip that supports PWM input dimming. It adopts analog dimming control mode throughout the process, and is designed for strobe-free and noise-free LED intelligent lighting applications. The BP2886X can achieve excellent dimming linearity and output current consistency, and is suitable for non-isolated accelerating LED constant current power supply with full range of input voltages of 85Vac~265Vac. The BP2886X chip integrates high-voltage start-up circuit and 500 power tube without VCC capacitors and auxiliary windings, only a few peripheral components are required to achieve excellent constant current characteristics, greatly saving system cost and volume.

The BP2886X chip has a high-precision current sampling circuit to achieve accurate LED constant current output and excellent line voltage regulation. BP2886X has multiple protection functions, including LED open circuit protection LED short circuit protection, chip temperature overheating regulation, etc.

The BP2886X is available in SOP-8 package.
