The THD-15N series models provide 15 Watt output power out of a very compact

shielded metal case that occupies only 1 inch² of board space. The converters work

with a high efﬁciency over the full load range and draw a very low input current at

no load conditions. All models have a wide 2:1 input voltage range and a precisely

regulated output voltage.

Typical applications for these converters are mobile equipment, instrumentation,

distributed power architectures in communication and industrial electronics and ev-

erywhere where space on PCB is critical.
