DESCRIPTION

The NML 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 2 watt output at 85°C.
