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.

PRODUCT OVERVIEW

The NTV series of 3kV isolation miniature

surface mounted DC/DC converters employ

leadframe technology and transfer moulding

techniques to bring all of the benefits of IC style

packaging to hybrid circuitry. The co-planar-

ity of the pin positions is based upon IEC

191-6:1990. The devices are suitable for all

applications where high volume production is

envisaged.

1. If components are required in tape and reel format suffix order code code with -R, e.g. NTV0505MC-R.

2. Calculated using MIL-HDBK-217F with nominal input voltage at full load.

3. 12V input types have typically 3% less load regulation change.

4. Supply voltage must be disconnected at the end of the short circuit duration.
