The TEN 20 series of DC/DC converters , comprising 18 different models, has been designed for a wide range of applications including communications, industrial systems and battery powered equipments. Full SMD-design with use of ceramic chip capacitors guarantees a high reliabil- ity and a long lifetime. Other features of this converters are internal filter to meet EN 55022, class A and FCC, level A and an extended temperature range of -40°C to +85°C.
The TEN 20 Series from Traco Power is a family of 20‑W DC/DC converters designed for communications, industrial systems, and battery‑powered equipment. The series offers a wide 2:1 input voltage range, high efficiency up to 89 %, and an extended operating temperature range of –40 °C to +85 °C.
The datasheet lists detailed electrical specifications such as input voltage ranges from 3.3 V to 75 V, output voltages from 3.3 V to 15 V, typical efficiencies of 81‑89 %, isolation voltage of 1500 VDC, and a fixed switching frequency of 330 kHz. Mechanical data include a shielded metal case, weight of 30 g, and dimensions with insulated baseplate pins.
