CS5106

CS5106 CS5106 Multi-Feature, Synchronous plus Auxiliary PWM Controller Description 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 house keeping. 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 speed, flexibility, reduced size and reduced component count are requirements. The controller contains the following features: Undervoltage Shutdown, Overvoltage Shutdown, Programmable Frequency, Programmable Synchronous NonOverlap 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 temperature and supply ranges of -40ûC to 125ûC and 9V to 16V respectively and is available in the 24 lead SSOP package.
