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 1.25 watt output at 85°C. For lower ripple,refer to output ripple reduction section. All specif cations typical at TA=25 ° C, nominal input voltage and rated output current unless otherwise specif ed.
