S4525S CCT Controller – Now in Stock at Regency Semiconductors
We are pleased to announce the availability of the S4525S CCT controller from BPSemi. This highly integrated IC is designed for color temperature tuning applications, offering a compact and cost-effective solution for LED lighting systems.
What is the S4525S?
The S4525S is a CCT (Correlated Color Temperature) controller with two integrated 400V thyristors and high-voltage JFET power supply circuits. It eliminates the need for a VCC capacitor and startup resistor, significantly reducing system cost and size. The device utilises stable ON-OFF detection technology to ensure state consistency in multi-module applications.
It is compatible with Flyback, Buck, Buck-Boost and other LED driving topologies, making it a versatile choice for a wide range of lighting designs.
