Description
BP9916D 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 BP9916D integrates a 500V power MOSFET.
With patent pending MOSFET driving technique, the
operating current of the IC is as low as 200uA. It
doesn’t need the auxiliary winding for VCC supply.
It can achieve excellent constant current performance
with very few external components, so the system
cost and size are minimized.
BP9916D 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 output voltage.
The BP9916D offers rich protections to improve the
system reliability, including LED short circuit
protection, VCC under voltage protection and
thermal regulation function.
