SD6800 Description
The SD6800 is a single stage primary side regulation (PSR) power factor correction (PFC) controller, specially designed for LED driver. The Device adopts constant on time operation to achieve high power factor. The SD6800 provides accurate constant current control and operates in boundary conduction mode (BCM) with high efficiency.
