PRODUCT OVERVIEW
All other variants 115
The NTA series of miniature surface mounted
DC-DC Converters employ leadframe
ABSOLUTE MAXIMUM RATINGS
technology and transfer moulding techniques
Internal power dissipation 700mW
to bring all of the benets of IC style
Input voltage VIN, NTA03 types 5.5V
packaging to hybrid circuitry. Co-planarity of the
Input voltage VIN, NTA05 types 7V
lead positions is based upon IEC 191-6:1990. The
Input voltage VIN, NTA12 types 15V
devices are suitable for all applications where
high volume production is envisaged.
1. If components are required in tape and reel format sufx order code with -R, e.g. NTA0505MC-R.
2. Calculated using MIL-HDBK-217F with nominal input voltage at full load.
