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.

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 NMR series ensures
ease of upgradeability.
