ISOLATED UNREGULATED DUAL OUTPUT DC/DC CONVERTER
BxxxxLS-1W SERIES
DESCRIPTION
The BxxxxLS-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.

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.
