military dc - dc converters series lfa xxda dual new version aluminum package isolated regulated 65 watts each channel , wide input range/18 - 36 vdc fully regulated, short circuit protected parallel operation available features: ? dual isolated outputs ? short circuit protection ? input voltage protection ? thermal, over temp. shutdown ? line regulation ? load regulation ? no external components required ? hi density, hi efficiency design ? remote shutdown ? trim capabilities ? fixed frequency - 100 khtz typical characteristics: frequency: 100 khtz base plate: max. +85o c operating temperature: see thermal chart: - 40o c to +85o c base plate, - 55o c to +85o c base plate. test conditions: 25o c ambient isolation base input: 2121 vdc isolation input output: 4 242 vdc isolation output to base: 1000 vdc storage temperature: - 55o c to +105o c series lfa: - 40oc to +85oc operating temperature surge -- meets mil std 704 vibration -- meets mil std 202 method 204 cond. d humidity -- meets mil std 202 method 106 shock -- meets mil std 202 method 213 cond. i altitude -- meets mil std 202 method 105 cond. d selected mil std 883 options also available stabilization bake -- mil std 883 method 1008 24 hrs ta=125o c burn in -- mil std 883 method 1015 160 hrs at 90o c, case temperature cycle -- mil std 883 method 1010 cond. b the pico lfa xxda series of high power dc - dc converters, allow a wide input voltage of 18 - 36 vdc, while maintaining a regulated output. they are fully safeguarded for over voltage, over temperature and continuous short circuit protection. the availability of dual isolated outputs, small size, and the capability of parallel operations as standard features should reduce your design and
component costs, while the fixed frequency operation h elps parallel connections for higher power requirements. this high density unit is assembled in full aluminum package in the usa with pico quality and component selection, allowing it to meet the most stringent military requirements.
