BP2888
Non-isolation Two Way Buck LED Driver
With Wall Switch Color Dimming
Description
Features
The BP2888 is an internal integrated high-voltage
power supplytwo way buck LED driver with wall
switch color dimming, and is suitable for
85Vac~265Vac universal input offline LED lighting.
The BP2888 can detect three switch status by DET pin,
cold, warm, mixed color, and mixed color current can
be controlled by adjusting RDIM1 / RDIM2 pin to
realize different brightness.
The BP2888 operates in critical conduction modethe
output current does not change with the inductance
and LED output voltage, and it achieves high
precision output current control, and excellent line
regulation and load regulation.
The BP2888 offers rich protection functions
including LED open/ short ProtectionVCC under
voltage protection, thermal shutdown function
