DC/DC Converter THN 15WI Series, 15 Watt Smallest encapsulated 15 W Converter 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 18-75 VDC Output voltage Trim UL 62368-1 IEC 62368-1 5 Vout models with trim up to 6 VDC The THN 15WI series is the latest generation of high performance DC/DC con- ideal for LDO applications verter modules setting new standards concerning power density. This product with 15 W comes in a encapsulated, shielded metal package with dimensions I/O isolation voltage 1500 VDC 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 volt- Very high efficiency up to 87% ages. Advanced circuit design provides high efficiency up to 87% which allows Operating temp. range: an operating temperature range of 40C to +85C (with derating) Further fea- 40C to +85C tures include remote On/Off and trimmable output. Typical applications for these converters are battery operated equipment, mobile instrumentation, dis- Remote On/Off control tributed power architectures in communication and industrial electronics and 3-year product warranty everywhere where space on PCB is critical.
