    The SD680X is a single stage primary side regulation (PSR) power factor correction (PFC) controller, built-in high voltage power MOSFET, specially designed for LED driver. 

    The Device adopts constant on time operation to achieve high power factor. 

    The SD680X provides accurate constant current control and operates in boundary conduction mode (BCM) with high efficiency.

    The Device adopts primary side regulation eliminating the opto-couple, secondary feedback control and loop compensation for reducing design and cost. 

   The SD680X provides completed protections such as short LED protection, open LED protection and over temperature protection, etc.
