PRODUCT OVERVIEW
The NTA 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 circuitry. Co-planarity of the
lead 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. If components are required in tape and reel format suffix order code code with -R, e.g. NTA0505MC-R.
2. Calculated using MIL-HDBK-217F with nominal input voltage at full load.
3. Supply voltage must be disconnected at the end of the short circuit duration.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
