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.
◆ No minimum load required
◆ Lead free design, RoHS compliant
◆ 3-year product warranty
