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.
