The UCC25600 high performance resonant mode controller is designed for dc-to-dc applicaTIons uTIlizing resonant topologies, especially the LLC half bridge resonant converter. This highly integrated controller implements frequency modulaTIon control and complete system funcTIons in only an 8-pin package. Switching to the UCC25600 will greatly simplify the system design, layout and improve time to market, all at a price point lower than competitive 16-pin device offerings.
The internal oscillator supports the switching frequencies from 30 kHz to 350 kHz. 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.
