The UCC28610 brings a new level of performance and reliability to the AC and DC consumer power supply solution.
A PWM modulation algorithm varies both the switching frequency and primary current while maintaining discontinuous or transition mode operation over the entire operating range. Combined with a cascoded architecture, these innovations result in efficiency, reliability, and system cost improvements over a conventional flyback architecture.
The UCC28610 offers a predictable maximum power threshold and a timed response to an overload, allowing safe handling of surge power requirements. Overload fault response is user-programmed for retry or latch-off mode. Additional protection features include output overvoltage detection, programmable maximum on-time, and thermal shutdown.
