Natural Interleaving™ Transition-Mode PFC Controller With Improved Audible Noise

Immunity

NATURAL INTERLEAVING FEATURES

SYSTEM FEATURES

•

Improved Audible Noise Performance

Soft Start on Overvoltage

Integrated Brownout

Improved Efficiency and Design Flexibility

over Traditional, Single-Phase Continuous

Conduction Mode (CCM)

•

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

•

Input Filter and Output Capacitor Current

Cancellation:

Inrush Safe Current Limiting:

–

Reduced current ripple for higher system

reliability and smaller bulk capacitor

–

Prevents MOSFET conduction during

inrush

–

Reduced EMI filter size

–

Eliminates reverse recovery events in

output rectifiers

•

Enables Use of Low-Cost Diodes without

Extensive Snubber Circuitry

•

Improved Light-Load Efficiency

Improved Transient Response

Complete System-Level Protection
