DC/DC Converters THL 20WI Series, 20 Watt Features ◆ Smallest encapsulated 20W converter! CB Ultra compact size: 1.0” x 1.0” x 0.4” 226037 Scheme IEC 60950-1 ◆ Shielded metal case with isolated baseplate ◆ Ultrawide 4:1 input voltage ranges ◆ Very high efficiency up to 90% ◆ Output voltage adjustable ◆ Remote On/Off control ◆ Operating temp. range –40°C to +75°C and up to +85°C 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 1.0”x 1.0”x 0.4”. All models have an ultra wide 4:1 input voltage range and precisely regulated output 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, distributed power architectures in communication and industrial electronics and everywhere where space on the PCB is critical.
