UCC25600D Datasheet PDF - TI

●The UCC25600D is a 8-pin High Performance Resonant Mode Controller designed for DC-to-DC applications using resonant topologies, especially the LLC half-bridge resonant converter. The internal oscillator supports the switching frequencies from 40 to 350kHz. This high-accuracy oscillator realizes the minimum switching frequency limiting with 4% tolerance, allowing the designer to avoid over-design of the power stage and, thus, further reducing overall system cost. The programmable dead time enables zero-voltage switching with minimum magnetizing current. This maximizes system efficiency across a variety of applications. The programmable soft-start timer maximizes design flexibility demanded by the varied requirements of end equipment using a half-bridge topology. By incorporating a 0.4A source and 0.8A sink driving capability, a low cost, reliable gate driver transformer is a real option.
