DESCRIPTION

The NTE series of 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 circuitr y. The devices are

fully compatible with CECC00802 to 280°C

which allows them to be placed and reflowed

with IC’s, thus reducing time and cost in

production. The co-planarity of the pin

positions is based upon IEC 191-6:1990.

The devices are suitable for all applications

where high volume production is envisaged.

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.

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

2 See derating curve.

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

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

5 If components are required in tape and reel format suffix order code with -R, e.g. NTE0505M-R
