Power Factor Collector
Description
It is Adaptable to a Discontinuous Mode of Operation that the S6503/P 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
