ISOLATED 1W SINGLE OUTPUT DC/DC CONVERTER
FxxxxS-1W SERIES
DESCRIPTION
The FxxxxS-1W series of DC/DC Converters is particularly suited to isolating and/or
converting DC power rails. The galvanic isolation allows the device to be configured to
provide an isolated negative rail in systems where only positive rails exist. The wide
temperature range guarantees startup from –40°C and full 1 watt output at 85°C. For lower
ripple, refer to output ripple reduction section.

Style
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..
