    SINGLE STAGE PRIMARY SIDE REGULATION PFC CONTROLLER FOR LED DRIVER
    
					
				
    
				
    
					
    
												
    
							
							
    
								
        The SD6898AH is a single stage primary side regulation (PSR) power factor correction (PFC) controller, built-in 650V high voltage power MOSFET, specially designed for LED driver. 
        The Device adopts constant on time operation to achieve high power factor. 
        The SD6898AH 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 SD6898AH provides completed protections such as short LED protection, open LED protection and over temperature protection, etc.
