SD6800TR

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. SOP-8-225-1.27 FEATURES  PSR Flyback topology  Boundary Conduction Mode  Low start current  Leading edge blanking  Constant on-time control  VCC over voltage protection  VCC under voltage lockout  Over temperature protection  Cycle by cycle current limiting  Peak current compensation  Short LED protection and Open LED protection APPLICATIONS  LED lamp  LED illumination with AC input ORDERING INFORMATION Part No. SD6800 SD6800TR Package SOP-8-225-1.27 SOP-8-225-1.27 Material Halogen free Halogen free Packing Tube Tape & reel HANGZHOU SILAN MICROELECTRONICS CO.,LTD http: //www.silan.com.cn Rev.:1.3 Page 1 of 8 Silan Microelectronics BLOCK DIAGRAM Clamp FB 2 CC MODULE 0.1V GM SD6800_Datasheet CS 3 CLAMP uvlo CS_O CS_PL PFC MO...
