1W to 2W Isolated DC-DC Converters

CUI Inc 1W to 2W Isolated DC-DC Converters are unregulated and cost-effective isolated modules that offer efficiency of up to 89%. These converters are housed in compact 4-, 6-, 7-, 8-, or 10- pin packages and operate at -40°C to +105°C temperature range. CUI Inc 1W to 2W Isolated DC-DC Converters are ideal for the conversion and isolation of DC rails for industrial, telecom, security, and machine control applications.
