PRODUCT DESCRIPTION

The NTF 1W series of surface mount DC/DC

converters offer a tightly regulated output voltage

in a true surface mount device, available with

three 2:1 input voltage ranges of 4-6V, 9-15V

and 18-36V. The NTF series’ employs 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.
