The CS5106 is a fixed-frequency, current-mode controller with one single NFET driver and one dual FET, synchronous driver. The synchronous driver allows for increased efficiency of the main isolated power stage and the single driver allows the designer to develop auxiliary supplies for controller power as well as secondary side housekeeping. In addition, because the synchronous drivers have programmable FET non-overlap, the CS5106 is an ideal controller for soft-switched converter topologies. The CS5106 is specifically designed for isolated topologies where the main switch and auxiliary switch operate on different clock phases.
The CS5106 is a multi-feature, synchronous plus auxiliary PWM controller designed specifically for isolated topologies. It operates as a fixed frequency, current mode controller featuring one single NFET driver and one dual FET synchronous driver to increase efficiency in the main isolated power stage.
Key features include programmable frequency and programmable synchronous non-overlap time, which makes it ideal for soft-switched converter topologies. The device also incorporates undervoltage shutdown, overvoltage shutdown, output undervoltage protection with a timer, and a controlled hiccup mode.
