S6503/P
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
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

S6503 電子部品, 半導体
Application Information
1. Main Inductor
L = η × (VO VP ) ×VP2 /(4VO × PO × f )
Where,
η: Efficiency (0.95)
VO: DC Link Voltage
VP: Input Peak Voltage
PO: Output Power
f: Switching Frequency
2. Resistor for Current Sense
RS = 1.75/ILP
Where,
ILP: Inductor Peak Current
3. Resistor for Multiplier
RML<0.69 x RMU / (VP0.69)
Where,
RMU: Under Resistor for Multiplier Input
RML: Lower Resistor for Multiplier Input
4. Resistor for Error Amplifier
REL = 2.5 x REU / (VO – 2.5)
Where,
REU: Under Resistor for Error Amplifier Inverting Input
REL: Lower Resistor for Error Amplifier Inverting Input
