  • Product Introduction
This UCC25600 high-performance resonant mode controller is designed to utilize DC-to-DC resonant topologies, especially for LLC half-bridge resonant converter applications. This highly integrated controller enables FM control and full system functionality in an 8-pin package. Switching to UCC25600 will greatly simplify system design, layout, improve time-to-market, and reduce all prices compared to competitor 16-pin device offerings.

The internal oscillator supports switching frequencies from 30 kHz to 350 kHz. This highly accurate oscillator switching frequency achieves a minimum tolerance limit of 4%, allowing designers to avoid "over-engineered" power stages, thereby further reducing overall system costs.

UC3864 TI 08+ 16PDIP The UC1861 IC - The 1868 series is ideal for the control of zero-current and zero-voltage switching quasi-resonant converters. The difference between this is from the UVLO threshold and the output selection of members of the various combination device family results. In addition, a single-pulse steering logic configuration scheme is available for both time zero-current systems (UC1865 - 1868) or shutdown times (UC1861 - 1864) for zero-voltage switching applications
