BP3125
High Precision PSR Constant Current LED Driver
Description
The BP3125 is a high precision primary-side feedback
and regulation controller for LED lighting, it operates
in constant current control mode and is designed to
work in inductor current discontinuous conduction
mode and extremely suitable for flyback convertor
under universal input, the output power of system
should be less than 12W.
The BP3125 integrates 600V power MOSFET. Since
adopting primary sense and feedback control
technology, the secondary sense and feedback circuit
is eliminated. The loop compensation components are
also removed while maintaining stability overall
operating conditions. The low component counts and
low BOM cost are realized.
Since using the proprietary high accurate current sense
method, the BP3125 realizes ±3% accuracy of LED
current along with excellent line regulation and load
regulation.
The BP3125 offers rich protection functions including
LED short circuit protection, LED open circuit
protection, die over-temperature protection, VCC over
voltage protection, VCC under voltage protection and
FB short circuit protection. All the protection features
are auto-recovery.
