AUK S6503P

S6503P
Semiconductor
Power Factor Collector
Description
It is Adaptable to a Discontinuous Mode of Operation that the S6503P is Advanced PFC (Power Factor
Correction) Controller for the High Density Switching Mode Power Supply and Electronic Ballast systems.
The Bulky External components are eliminated in the Internal Start-up circuits, though it is taken in
Independent Boost Converter Operation. What is more, instead of the External components, the Low
Pass Filter is mounted in Internal Current Sense block. Internal Clamping of the Error Amplifier and
Multiplier Output improve turn on Overshoot Characteristics and Current Limiting. The One of features is
able to prevent Abnormal Condition, Open Lamp & Over Voltage.
Features
• Very Precise Adjustable Output OVP (Dynamic & Static OVP Function)
• Extremely Low Start-Up Current
• Low Operating Supply Current
• Internal Start-Up Timer
• Power Factor Maximizer & THD Minimizer Circuit
• Complete Wide Range Operation
• Feedback Open Protection
• Minimum On Timer
• Current Sense Filter On Chip
• Disable Function
• Extremely Minimized External Part Counts High Speed Response Time
Applications
• Switching Mode Power Supply (SMPS)
• Electronic Ballast
Ordering Information
Type NO.
