Power Control IC
The BP3519 is a compact power control IC designed for isolated flyback power supplies that need both constant current (CC) and constant voltage (CV) regulation. It is ideal for battery chargers, LED drivers, standby power supplies, and auxiliary power supplies where accurate output control and energy efficiency are important. This PSR CCCV controller IC uses primary side regulation, so it does not require an optocoupler. That helps reduce BOM cost, simplify circuit design, and improve reliability while maintaining ±5% output accuracy.
