The THL 20WI series is the latest generation of dc-dc converter modules with highest

power density. The product achieves 20 Watt output power while it comes in a metal

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

All models have an ultra wide 4:1 input voltage range and precisely regulated out-

put voltages. Highest efﬁciency of up to 90% makes this product very reliable and

applicable in temperature ranges of up to +75°C or +85°C with optional mounted

heat sink. Typical applications are in mobile equipments, instrumentation, distribut-

ed power architectures in communication and industrial electronics and everywhere

where space on the PCB is critical.
