The THN-15WI 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”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

voltages. Advanced circuit design provides high efﬁciency up to 87% which allows

a operating temperature range of –40°c to +85°C (with derating) Further features

include remote On/Off, trimable output and Basic Insulation. This product is fully

compliant to RoHS directive. Typical applications for these converters are battery

operated equipment, mobile instrumentation, distributed power architectures in

communication and industrial electronics and everywhere where space on PCB is

critical.
