Infineon Technologies ICLS6022J

Beschreibung

ICLS6x Series controllers employ a fixed-frequency operation mode optimized for offline LED lighting. The integrated constant power function (patented by Infineon Techologies AG) and the frequency jitter enable highperformance without investment of too much effort in stabilization of the system and filtering in terms of EMC.A wide VCC range up to 26 V is provided by use of BiCMOS technology to cover changes in the auxiliary supply voltage if a CV/CC regulation is implemented on the secondary side. Auto Restart Mode is entered in the case of overtemperature, VCC overvoltage, output open loop or overload and VCC undervoltage. If an open load event occurs, the device enters the so-called Floating Load Protection (FLP) mode to protect the LED against destruction. The dimensions of the transformer and the secondary diode can be reduced owing to the internal precise peak current limitation to yield greater cost efficiency.
