Function : Natural Interleaving™ DUAL-PHASE TRANSITION-MODE PFC CONTROLLER
Maker : Texas Instruments

Pinouts :
UCC28060 datasheet

Description :

DESCRIPTION
Optimized for high-volume consumer applications, this solution extends the advantages of transition mode—high efficiency with low-cost components—to higher power ratings than previously possible. By utilizing a Natural Interleaving technique, both channels operate as masters (that is, there is no slave channel) synchronized to the same frequency. This approach delivers inherently strong matching, faster responses, and ensures that each
channel operates in transition mode.

NATURAL INTERLEAVING FEATURES
• Easy Phase Management Facilitates Compliance to Light-Load Efficient Standards
• FailSafe OVP with Dual Paths Prevents Output Over-voltage Conditions Caused by
Voltage-Sensing Failures
• Sensorless Current Shaping Simplifies Board Layout and Improves Efficiency
• Inrush Safe Current Limiting:
– Prevents MOSFET conduction during inrush
– Eliminates reverse recovery events in output rectifiers

SYSTEM FEATURES
• Cost Savings
• Improved Efficiency and Design Flexibility over Traditional, Single-Phase Continuous
Conduction Mode (CCM)
• Input Filter and Output Capacitor Current Cancellation:
– Reduced current ripple for higher system
reliability and smaller bulk capacitor
– Reduced EMI filter size
• Enables Use of Low-Cost Diodes without
Extensive Snubber Circuitry
• Improved Light-Load Efficiency
• Improved Transient Response
• Complete System-Level Protection
• 1-A Source/1.8-A Sink Gate Drivers
• Operating Temperature Range: –40°C to +125°C in an SOIC 16-pin package

APPLICATIONS
• 100-W to 800-W Power Supplies
• LCD, Plasma, and DLP®TVs
• Computer Power Supplies
• Entry Level Servers
• Electronic Lighting Ballasts
