The THN 15WI series is the latest generation of high performance DC/DC con-
verter modules setting new standards concerning power density. This product
with 15 W comes in a encapsulated, shielded metal package with dimensions
of only 1.0" x 1.0" x 0.4" and occupies 50% (!) less board space. All models
have ultra wide 4:1 input voltage range and precisely regulated output volt-
ages. Advanced circuit design provides high efficiency up to 87% which allows
an operating temperature range of –40°C to +85°C (with derating) Further fea-
tures include remote On/Off and trimmable output. Typical applications for
these converters are battery operated equipment, mobile instrumentation, dis-
tributed power architectures in communication and industrial electronics and
everywhere where space on PCB is critical.
