UCC28060 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.
Complete system-level protections feature input brownout, 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.
