描述 Description

The BP2866B is a high precision buck constant

current LED driver. The device operates in critical

conduction mode and is suitable for 85Vac~265Vac

universal input offline LED lighting.

The BP2866B integrates a 500V power MOSFET,

with patented demagnetization detection technology.

High - voltage JFET power supply technology,

which can save VCC capacitor and starting resistors,

minimize the system cost and size.

The BP2866B utilizes patent pending current control

method. It can achieve precise output current and

excellent line regulation. The driver operates in

critical conduction mode, the output current does not

change with the inductance and LED output voltage.

The BP2866B offers rich protection functions to

improve the system reliability, including LED short

circuit protection, VCC under voltage protection,

thermal regulation function
