PSR Isolated CCCV Driver IC
Description
BP3519 is PSR isolated CCCV driver IC. The device operates in discontinued conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting. The BP3519 can perform in high accurate CCCV without external pensation capacitor, benefit to save the BOM size and cost.
The BP3519 supports multiple control mode of PWM and PFM, which contribute to very low standby power, high efficiency and minimum no load noise.
The BP3519 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...
