The THN-15 series is the latest generation of high performance dc-dc converter
modules setting new standards concerning power density. This product with
15W comes in a encapsulated, shielded metal package with dimensions of only
1.0”x1.0”x 0.4” and occupies 50%(!) less board space. All models have wide 2:1
input voltage range and precisely regulated, isolated output voltages. Advanced
circuit design provides high efficiency up to 88% which allows a operating tem-
perature range of –40°C to +85°C (with derating) Further features include remote
On/Off and trimmable output. Typical applications for these converters are mobile
equipment, instrumentation, distributed power architectures in communication and
industrial electronics and everywhere where space on PCB is critical.
