TDK-Lambda has extended its CC-E range of DC-DC converters with the introduction of new 15 W and 30 W versions. Each CC-E power range comprises 32 models and is available in both surface mount and through-hole packages with applications in factory automation systems, computers and communications devices.
A proprietary TDK low-loss ferrite core material ensures high efficiency of operation resulting in a compact size with a low profile. For instance, the 30 W CC30-4805SHF-E model measures just 37,9 x 31,6 x 6,5 mm, achieves an efficiency of 92,5% and a power density of 3,9 W/cm³.
Accepting a nominal input of either 24 V or 48 V, these converters are available in the most popular output voltages from 3,3 to 15 V d.c. Operating temperature is from -40°C to +85°C ambient with a choice of input to output isolation of 500 V d.c. or 1500 V d.c. Representing an upgrade of the existing products, added functions include parallel operation, simultaneous startup and startup delay functions, as well as remote on/off and output trim feature. Standard protection features include low-voltage, over-voltage and over-current conditions.
The CC-E series is approved to a wide range of safety standards, including UL/CSA/EN60950-1 and all models carry the CE mark, according to the LV directive. Their design eliminates the use of tantalum and electrolytic capacitors to ensure long life and high reliability, which is supported by a five-year warranty.
