Working Principle of UCC 28600D

The UCC 28600D uses an asymmetrical quasi-resonant switching technique to provide high switching frequency and efficiency, while operating in either AC-DC or DC-DC topologies. This technique works by switching the main power stage transistors at a frequency above its resonance frequency, which reduces losses and increases efficiency. During the cycle of operation, each half-cycle of the switching frequency is used for AC-DC or DC-DC power conversion. The rectified output voltage is then further regulated and switched around a set reference voltage. The precise voltage reference, combined with the advanced switching technique, ensures accurate and stable output voltages that are suitable for a wide range of applications.
