BP2812
Constant Current Controller For
Non-isolated Buck LED Driver
Description
The BP2812 is a high precision constant current
controller, designed for non-isolated buck LED
driver. It can operate under universal AC input or
12V~600V DC input. The BP2812 integrates 600V
power MOSFET, so it can achieve excellent constant
current performance with very few external
components
The BP2812 uses high precision current sense circuit
and patent method for constant current control, to
achieve high precision output current and excellent
line regulation. The BP2812 operates in inductor
current critical mode. The LED current is constant
over wide range of inductance variation and the LED
output voltage, so the load regulation is excellent.
The BP2812 uses patent source driver architecture.
The operation current is 200uA only, so the auxiliary
winding is not needed. It can simplify the system
design and reduce the system cost.
The BP2812 offers rich protection functions,
including LED short circuit protection, current sense
resistor short circuit protection and over temperature
protection.

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.
