BRIEF OVERVIEW
series family highest performance DC/DC converters, incorporating single ended forward converter technology, including synchronous rectification provide highest possible efficiency. DC/DC converter been designed meet especially requirements telecom environment, which size, efficiency, height, operating temperature. footprint, i.e. input output pins industry compatible, profile case size 1.60" 2.0" 0.40". converter family operates 400kHz fixed frequency does require external input/output filtering. output power rated Watts, utilizing also no-load operation. Other features include: under voltage lockout, short circuit protection, ripple/noise, trim capability, optional temperature shutdown, over current protection, remote on/off control.
