DESCRIPTION
The BP3126 integrates 650V power MOSFET. Since adopting primary sense and feedback control technology, the secondary sense and feedback circuit is eliminated. The low component counts and low BOM cost are realized. Since using the proprietary high accurate current sense method, the BP3126 realizes ±3% accuracy of LED current along with excellent line regulation and load regulation. The BP3126 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. Typical ApplicationFEATURES
