BP2886B

BP2886X is a high-precision buck LED constant-current driver IC with PWM dimming input, operating entirely in analog dimming control mode, specifically designed for flicker-free and noise-free LED smart lighting applications. The BP2886X achieves excellent dimming linearity and output current consistency, suitable for non-isolated buck LED constant-current power supplies with a full input voltage range of 85Vac~265Vac. The BP2886X integrates a high-voltage startup circuit and a 500V power transistor, eliminating the need for a VCC capacitor and auxiliary winding. With minimal external components, it delivers excellent constant-current characteristics, significantly reducing system cost and board space. The BP2886X incorporates a high-precision current sensing circuit to achieve accurate LED constant-current output and excellent line voltage regulation. The BP2886X features multiple protection functions, including LED open-circuit protection, LED short-circuit protection, and over-temperature thermal regulation. The BP2886X is available in a SOP-8 package.
