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.
