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. Pin

compatibility with the NME and LME ensures

ease of upgradeability.

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.
