DC/DC Converter THD 15N Series, 15 Watt Highest power density in DIP 24 package Shielded metal case with isolated Baseplate Very high efficiency up to 91% Wide 2:1 input ranges UL 62368-1 IEC 62368-1 No minimum load required The THD 15N series models provide 15 Watt output power out of a very com- Input filter meets EN 55022 class A pact shielded metal case that occupies only 1 inch of board space. The con- without external components verters work with a high efficiency over the full load range and draw a very low input current at no load conditions. All models have a wide 2:1 input voltage I/O isolation voltage 1500 VDC range and a precisely regulated output voltage. Typical applications for these Operating temp. range : 40C to converters are mobile equipment, instrumentation, distributed power architec- +85C tures in communication and industrial electronics and everywhere where space on PCB is critical Remote On/Off control Industry standard pinout Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
