The THL 25 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 2:1 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.
