Optimized for high-volume consumer applications, this solution extends the advantages of the transition mode, high and low efficiency cost components, and may have higher power ratings than before. Utilizing a natural staggered technology, dual-channel operationMasters(that is, no slave channels) to synchronize to the same frequency. This approach provides an inherently powerful tie-in, faster response, and ensures that the transition mode in each channel operates.
Complete system-level functionality, input undervoltage protection, output overvoltage, open-loop, overload, soft-start, phase fault detection, and thermal shutdown. The additional fail-safe overvoltage protection (OVP) feature prevents an intermediate voltage that, if undetected, could lead to catastrophic short-circuit protection device failure.
