Description

• Parameters: SINGLE STAGE PRIMARY SIDE REGULATION PFC CONTROLLER FOR LED DRIVER
• Description: The SD7800 is a single stage primary side regulation (PSR) power factor correction (PFC) controller, specially designed for flyback LED driver. The SD7800 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 SD7800 adopts constant on time operation to achieve high power factor. Due to p
