BP9916B
Non-isolated Buck Offline LED Driver
Description
BP9916B 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 BP9916B integrates a 500V power MOSFET.
With patent pending MOSFET driving technique, the
operating current of the IC is as low as 180uA. 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.
BP9916B 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 BP9916B offers rich protections to improve the
system reliability, including LED short circuit
protection, VCC under voltage protection and
thermal regulation function.

Application Information
The BP9916B is a high performance non-isolated
Buck converter specially designed for LED lighting.
The device integrates a 500V power MOSFET. With
very few external components, the converter
achieves excellent constant current control. And it
does not need auxiliary winding for powering the IC
or voltage sensing, hence the system size and cost is
greatly reduced.
Start Up
After system powered up, the VCC pin capacitor is
charged up by internal HV JEFT. When the VCC pin
voltage reaches the turn on threshold, the internal
circuits start operating. The HV JEFT will still
supply operating current when the IC is working and
keep the VCC voltage at 7.3V.
Constant Current Control
Cycle by Cycle current sense is adopted in BP9916B,
the CS pin is connected to the current sense
comparator, and the voltage on CS pin is compared
with the internal 600mV reference voltage. The
MOSFET will be switched off when the voltage on
CS pin reaches the threshold. The CS comparator
includes a 500ns leading edge blanking time.
