3KV ISOLATED UNREGULATED DUAL 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.
