BP2836D
Non-isolated Buck Offline LED Driver
Description
The BP2836D 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 BP2836D integrates a 500V power MOSFET.
With patent pending MOSFET driving technique, the

operating current of the IC is very low. So it doesn’t

need the auxiliary winding for supplying the chip. It
can achieve excellent constant current performance
with very few external components, so the system
cost and size are minimized.
The BP2836D 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 BP2836D offers rich protection functions to
improve the system reliability, including LED open
circuit protection, LED short circuit protection, VCC
under voltage protection, CS resistor short circuit
protection and thermal regulation function.

Note 1: Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. Under “recommended operating

conditions” the device operation is assured, but some particular parameter may not be achieved. The electrical characteristics table defines the operation

range of the device, the electrical characteristics is assured on DC and AC voltage by test program. For the parameters without minimum and maximum
value in the EC table, the typical value defines the operation range, the accuracy is not guaranteed by spec.

Note 2: The maximum power dissipation decrease if temperature rise, it is decided by TJMAX, θJA, and environment temperature (TA). The maximum power

dissipation is the lower one between PDMAX = (TJMAX — TA)/ θJA and the number listed in the maximum table.

General Description
The BP2808 is a current mode control LED driver IC.
The BP2808 can support DC voltage which ranges
from 12V to 600V, with duty cycle up to 100%. The
BP2808 can be used in non-isolation LEDs driving

system and can support AC supply voltage from 85V to

265V. The BP2808 uses patented technique for source
driver and constant current compensation, so LEDs

current has ±3% accuracy with AC supply voltage

variation from 85V to 265V. What’s more, the patented
technique for the driving scheme ensures 90% higher
efficiency in the application of 18W LEDs lighting with
AC voltage range from 85V to 265V. In AC voltage
range from 85V to 265V, the BP2808 can drive
3W-36W LEDs array which is widely used in
E14/E27/PAR30/PAR38/GU10 lighting and tube LEDs
lighting.
The BP2808 has multiple LED protections, including
LED open-circuit protection, LED short-circuit
protection and thermal shutdown protection. If system
has a failure, the BP2808 will operate in protection
mode until system recovers.
The BP2808 is available in SOP8 packages.
