Overview

Silan Microelectronics SD6800_Datasheet SINGLE STAGE PRIMARY SIDE REGULATION PFC CONTROLLER FOR LED DRIVER 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.
