DC/DC Converters THL 20WI Series, 20 Watt Features Smallest encapsulated 20W converter 226037 IEC 60950-1 Ultra compact size: 1.0 x 1.0 x 0.4 Shielded metal case with isolated baseplate Ultrawide 4:1 input voltage ranges Very high efcfi iency up to 90% Output voltage adjustable Remote On/Off control Operating temp. range 40C to +75C and up to +85C with heat-sink I/O isolation voltage 1500 VDC Lead free design, RoHS compliant 3-year product warranty 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 1.0x 1.0x 0.4. All models have an ultra wide 4:1 input voltage range and precisely regulated out- put voltages. Highest efcfi iency of up to 90% makes this product very reliable and applicable in temperature ranges of up to +75C or +85C with optional mounted heat sink. Typical applications are in mobile equipments, instrumentation, distributed power architectures in communication and industrial electronics and everywhere where space on the PCB is critical.
