The THN 20WI series models are high performance dc-dc converters. They achieve

20 Watt output power and come in a small size metal casing (1.0” x 1.0” x 0.4”).

The models feature an ultra-wide 4:1 input voltage range while the output voltages

are precisely regulated even under no load conditions. Highest efﬁciency of up to

90% makes this product very reliable and applicable in temperature ranges of up to

85°C. The low no-load input current characteristics and the remote On/Off control

make these converters an ideal solution for battery operated systems. Typical ap-

plications are in mobile equipment, instrumentation, distributed power architectures

in communication and industrial electronics and everywhere where space on the

PCB is critical.
