CUI Inc. – Rugged, Efficient, Economical DC/DC Converters Satisfy a Broad Range of Applications

CUI’s 1W, 2W and 3W isolated DC/DC converters are ideal for converting and isolating voltage rails, and are housed in space efficient packages allowing use close to the point of load.

In total, over 90 different variants are available, offering a choice of regulated and unregulated outputs at standard voltages from 3.3V to 48V.

These DC/DC converters are housed in SIP, DIP or surface mount packages, and have industry standard pin configurations. An ultra wide operating temperature range from -40°C up to +105°C and an encapsulated case make the units ideal for applications that may experience challenging operating conditions. The converters have been designed to maximize efficiency under light-load and no-load conditions, making them well suited for portable and battery-powered equipment.
