The syn- chronous driver allows for increased efficiency of the main iso- lated power stage and the single driver allows the designer to devel- op auxiliary supplies for controller power as well as secondary side house keeping. In addition, because the synchronous drivers have programmable FET non-over- lap, the CS5106 is an ideal con- troller for soft-switched converter topologies. The CS5106 is specifically designed for isolated topologies where speed, flexibility, reduced size and reduced component count are requirements. The controller con- tains the following features: Undervoltage Shutdown, Overvoltage Shutdown, Programmable Frequency, Programmable Synchronous Non- Overlap Time, Master/Slave Clocking with Frequency Range Detection, Enable, Output Undervoltage Protection with Timer, 20mA 5V Output, 80ns PWM propagation delay, and Controlled Hiccup Mode. The CS5106 has junction tempera- ture and supply ranges of -40ûC to 125ûC and 9V to 16V respectively and is available in the 24 lead SSOP package.
