ISOLATED UNREGULATED DUAL OUTPUT DC/DC CONVERTER
BxxxxS-1W SERIES
When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external capacitance
value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the additional external
capacitance for reliable start up.
