DC/DC Converter TDN 1WISM Series, 1 Watt

Mod els

• Compact SMD package

13,2  9,1  10,2 mm

• Fully regulated outputs

• I/O-isolation 1‘500 VDC

• Operating temperature range

–40°C to +90°C without derating

• Short circuit protection

• Remote On/Off

• 3-year product warranty

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 cm

. Full

load operation is reliable up tp 90°C environment temperature. With 1’500 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.
