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
