DC/DC Converters THD 15 Series, 15 Watt RoHS compliant pending Features ◆ Smallest encapsulated 15W Converter Ultra compact Size: 25.4x25.4x10.2mm ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ Single- and Dual Output Models I/O- Isolation Voltage 1500VDC High Efficiency up to 87% Operating Temp. Range: -25°C to 71°C Remote On/Off Industry Standard Pinout Lead free Design, RoHS compliant 3 Year Product Warranty The THD-15 series is the latest generation of high performance 15W dc-dc converter modules setting new standards concerning power density. This product comes in a encapsulated package with dimensions of only 25.4 x 25.4 x 10mm and therefore occupies 50%(!) less board space than existing 15W converters. All models have wide 2:1 input voltage range and precisely regulated, isolated output voltages. Built-in filters for both input and output minimizes the need for external filtering. Further features include remote On/Off and short circuit protection. Typical applications for these converters are battery operated equipment, instrumentation, distributed power architectures in communication and industrial electronics and everywhere where space is limited on the PCB.
