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.
The Device adopts primary side regulation eliminating the opto-couple,
secondary feedback control and loop compensation for reducing design
and cost.
The SD6800 provides completed protections such as short LED
protection, open LED protection and over temperature protection, etc.
