The SD7880 is a single stage primary side regulation (PSR) high power factor LED driver with dimming function, it has PWM and linear dimming functions, with dimming depth up to 5%, it is mainly used in isolated flyback smart LED lighting system.
The SD7880 provides accurate constant current control and operates in boundary conduction mode (BCM) with high efficiency. It adopts primary side regulation eliminating the opto-couple, secondary feedback control and loop compensation, which effectively simplifies the design and reduces the system cost.
The SD7880 provides complete protections such as short LED protection, open LED protection and over temperature protection, etc.
