DC/DC Converter TDN 1WISM Series, 1 Watt * Compact SMD package 13,2 x 9,1 x 10,2 mm * Fully regulated outputs * I/O-isolation 1`600 VDC * Operating temperature range -40C to +90C without derating * Short circuit protection * Remote On/Off * 3-year product warranty * Designed to meet UL 62368-1 (UL 60950-1) Also see: TDN 1WI, DIP version www.tracopower.com/products/tdn1wi.pdf The TDN 1WISM Series comprises 1 Watt fully regulated, high performance DC/ DC converters. They come in a compact cubical package of only 1.23 cm3. Full load operation is reliable up tp 90C environment temperature. With 1'600 VDC I/O-isolation voltage, external On/Off, 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 (4:1) and minimum load is not required. The functional I/O-isolation system is designed to meet IEC/EN 62368-1 with a test voltage (60 s) of 1500 VDC. Models Order code Input voltage Output voltage Output current max. Efficiency typ.
