BP2519
PSR Isolated CCCV Driver IC
Description
BP2519 is non-isolated CCCV driver IC. The device
is suitable for 85Vac~265Vac universal input offline
LED lighting. The BP2519 can perform in high
accurate CCCV without external compensation
capacitor, benefit to save the BOM size and cost.
The BP2519 supports multiple control mode of PWM
and PFM, which contribute to very low standby power,
high efficiency and minimum no load noise.
The BP2519 offers rich protection functions to
improve the system reliability, including cycle by
cycle peak current control, load open/short protection,
VCC under/over voltage 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.
Note 3: Human Body mode, 100pF capacitor discharge on 1.5kΩ resistor.
