Texas Instruments' model UCC28061D is a power management IC optimized for consumer applications related to audible noise cancellation, extending the benefits of high conversion-mode efficiency with low-cost components to higher power ratings than previously possible. By using natural interleaving techniques, both channels operate as master channels (ie, no slave channels) synchronized to the same frequency. This approach provides an inherently strong match, faster response, and ensures that each channel operates in transition mode.
Complete system level protection features include input undervoltage, output overvoltage, open loop, overload, soft start, phase failure detection and thermal shutdown. An additional FailSafe overvoltage protection (OVP) feature protects against intermediate voltage shorts that, if undetected, could lead to catastrophic equipment failure.
