1NATURAL INTERLEAVING FEATURES

23· Phase Management Capability

· 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

· Improved Audible Noise Performance

· Soft Start on Overvoltage

· Integrated Brownout

· 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

APPLICATIONS

· 100-W to 800-W Power Supplies

· Gaming

· D to A Set Top Boxes

· Adapters

· LCD, Plasma and DLP™ TVs

· Home Audio Systems
