Resumen del producto
The UCC28063AD is a natural interleaving transition-mode Power Factor Correction (PFC) Controller with improved audible noise immunity. It is identical to UCC28063 with the exception that the TSET pin Open/Short Fault Detect and the CS pin Open Fault Detect features are removed. Removal of these Fault Detect features provides a higher degree of noise immunity to provide increased ride-through for applications where significant voltage noise could be coupled onto the TSET or CS pins during conditions of fast transient, surge or impulse noise on the AC Supply. By utilizing a natural interleaving technique, both channels operate as masters 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.
