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.


• 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
