onsemi NCL30488B Single Stage CC/CV PSR Controllers

onsemi NCL30488B Single Stage CC/CV PSR Controllers are high PF single-stage constant current and constant voltage PSR PWM controllers. The NCL30488B is used for Flyback/Buck-Boost/Sepic/Boost. This controller operates in a QR mode to provide high efficiency. Thanks to a novel control method, the device is able to tightly regulate a constant LED current from the primary side. The device is highly integrated with a minimum number of external components. A robust suite of safety protection is built in to simplify the design.
