DC/DC Converters THL 25WI Series, 25 Watt Features ◆ Highest power density 25W converter! CB UL 60950-1 Ultra compact design: 1.0” x 1.0” x 0.4” Scheme IEC 60950-1 ◆ Shielded metal case with isolated baseplate ◆ Ultra wide 4 : 1 input voltage ranges ◆ Very high efficiency up to 90% ◆ Output voltage adjustable ◆ Remote On/Off control ◆ Operating temp. range –40°C to +80°C and up to +85°C with heat-sink ◆ I/O isolation voltage 1500 VDC ◆ 3-year product warranty The THL 25WI series is the latest generation of dc-dc converter modules with highest power density. The product achieves 25 Watt output power and comes in a metal case with small dimensions of only 1.0”x 1.0”x 0.4”. All models have a wide 4:1 input voltage range and precisely regulated output voltages. High efficiency of up to 90% makes this product very reliable and applicable in temperature ranges of up to +80°C or up to +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.
