【規格說明】
Silergy, SY5803 - Single stage Buck-Boost PFC controller
• Valley turn-on of the MOSFET to achieve low switching losses

• Aux-winding for ZCS detection and bias current optional
• 0.3V current sense reference voltage leads to a lower sense resistance thus a lower conduction loss
• Internal high current MOSFET driver: 1A  sourcing and 2A sinking
• Low start up current: 15µA typical
• Reliable short LED and Open LED protection
• Power factor >0.90 with single-stage conversion
• Compact package: SO8


NXP, SSL2129A
• Superb mains-dimmable LED driver solution (both leading and trailing edge phase cut dimmers)

• Buck driver ICs
   -Integrated 300 V MOSFET (SSL21082A)
   -Integrated 600 V MOSFET (SSL21084A)
• Highest efficiency due to:
   - Power-efficient boundary conduction mode
   - Start-up JFET
• High power factor (>0.9)
• Full range of internal protections
• Compatible with wall switches with built-in indication light during standby



Richtek, RT7304, Primary-Side-Regulation LED Driver Controller with Active PFC
• Tight LED Current Regulation

• No Opto-Coupler and TL431 Required
• Power Factor Correction (PFC)
• Quasi-Resonant
• Maximum/Minimum Switching Frequency Clamping
• Maximum/Minimum On-Time Limitation
• Wide VDD Voltage Range (up to 25V)
• Multiple Protection Features Full range of internal protections
