DC/DC Converters THN 15WI Series, 15 Watt CB Scheme Features ◆ Smallest encapsulated 15W Converter! UL 60950-1 UL 60950-1 Ultra compact size: 1.0” x 1.0” x 0.4” ◆ Shielded metal case with isolated baseplate ◆ Ultrawide 4:1 input ranges 9-36 VDC or 18-75VDC ◆ Output voltage Trim ◆ I/O isolation voltage 1500 VDC ◆ Very high efficiency up to 87% ◆ Operating temp. range : –40°C to +85°C ◆ Remote On/Off control ◆ Industry standard pinout ◆ 3-year product warranty The THN-15WI series is the latest generation of high performance dc-dc converter modules setting new standards concerning power density. This product with 15W comes in a encapsulated, shielded metal package with dimensions of only 1.0”x 1.0”x 0.4” and occupies 50% (!) less board space. All models have ultra wide 4:1 input voltage range and precisely regulated output voltages. Advanced circuit design provides high efficiency up to 87% which allows a operating temperature range of –40°C to +85°C (with derating) Further features include remote On/Off and trimmable output. Typical applications for these converters are battery operated equipment, mobile instrumentation, distributed power architectures in communication and industrial electronics and everywhere where space on PCB is critical.
