The THL 25WI series is the latest generation of dc-dc converter modules with highest

power density. The product achieves 25 Watt output power and comes in a metal

case with small dimensions of only 1.0”x 1.0”x 0.4”.

All models have a wide 4:1 input voltage range and precisely regulated output volt-

ages. High efﬁciency of up to 90% makes this product very reliable and applicable

in temperature ranges of up to +80°C or up to +85°C with optional mounted heat

sink. Typical applications are in mobile equipments, instrumentation, distributed

power architectures in communication and industrial electronics and everywhere

where space on the PCB is critical.
