DC/DC Converter TRN 1SM Series, 1 Watt * Compact SMD package 11,9 x 11,3 x 8,0 mm * Fully regulated outputs * Input Voltage range 4.5-13.2, 9-18, 18-36, 36-75 VDC * I/O-isolation 1`600 VDC * Operating temperature range -40C to +90C without derating * Short circuit protection * 3-year product warranty * Designed to meet UL 62368-1 (UL 60950-1) The TRN 1SM Series comprises 1 Watt fully regulated, high performance DC/ DC converters. They come in a compact cubical package of only 1.07 cm3. Full load operation is reliable up tp 90C environment temperature. With 1'600 VDC I/O-isolation voltage, and short current protection they cover a wide range of application when space is limited. The input of the converters is designed for a wide voltage range (2:1) and minimum load is not required. The functional I/Oisolation system is designed to meet IEC/EN 62368-1 with a test voltage (60 s) of 1600 VDC. Models Order code Input voltage Output voltage Output current max. Efficiency typ.
