Optimized for consumer applications concerned with audible noise elimination, 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.

Expanded system level protections feature input brownout and dropout recovery, output over-voltage, open-loop, overload, soft-start, phase-fail detection, and thermal shutdown. The additional FailSafe over-voltage protection (OVP) feature protects against shorts to an intermediate voltage that, if undetected, could lead to catastrophic device failure. Advanced non-linear gain results in rapid, yet smoother response to line and load transient events. Reduced bias currents improve stand-by power efficiency. Special line-dropout handling avoids significant current disruption and minimizes audible-noise generation.
