The THN-20 series is the latest generation of high performance dc-dc converter
modules with highest power density. The product achieves 20W 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 wide 2:1 input voltage range and precisely regulated output
voltages, even under no load conditions. 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. Together with low input current characteristics at
minimal load and remote On/Off control these converters are the ideal solution for
battery-operated systems. Typical applications are in mobile equipments, instrumen-
tation, distributed power architectures in communication and industrial electronics
and everywhere where space on the PCB is critical.
