Efficiency is up to 93%. This not only minimises heat loss through dissipation but also means that heatsinks are not required, to save space and mounting costs.
There are seven non-isolated dc-dc converters in the series range from 1.65-12W, depending on the model. Each version is also available with a 90 degree pin formation (denoted with an L suffix).
The regulators have low ripple and low noise operation and a MTBF of >2,000,000 hours. Operating temperature is -40 to +85°C and all models have short circuit protection and thermal shutdown safety functions. They are also RoHS-compliant.
The K78Uxx regulators are supplied in a SIP3 package and are pin-compatible with Mornsun’s LM78xx linear regulators.
