K78Uxx-500R3 Series Wide Input DC-DC Converters
24th January 2022 K78Uxx-500R3 Series
Wide Input DC-DC Converter Series in a Space Saving Package
Relec Electronics offers the latest model, the K78Uxx-500R3 Series, in a space saving SIP (Single in-line Package).
These high-efficiency K78Uxx-500R3 Series & K78Uxx-500R3L Series of switching regulators have been designed by Mornsun Power, and are ideal for use in space constrained and cost-conscious designs. These wide input DC-DC switching regulators are now available from Relec Electronics.
The 12W switching regulars are offered in an extremely wide input range of 9.0 – 90Vdc and with outputs ranging from 3.0 – 24Vdc.
Efficiency is up to 93% to minimise heat loss through dissipation. It also means that heatsinks are not required, resulting in space savings and reduced mounting costs.
The seven non-isolated DC-DC converters in the series range from 1.65-12W, depending on the model, provide 500mA of regualted power. Each version is also available with a 90 degree pin formation (denoted with an L suffix).
Characteristics include low ripple and low noise operation, with 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 the LM78xx linear regulators and can be used to directly replace them.
Short Lead-times & Competitively Priced
Many of the Mornsun DC-DC Converters are 100% compatible with devices from other manufacturers, and are available today with the industry’s shortest lead-times and benchmark pricing. In addition to standard AC-DC and DC-DC Power Supplies, Mornsun also welcomes enquiries for custom applications.
Here at Relec we are a happy to offer free of charge samples, many of which we have in stock for immediate delivery. We will also offer full technical support to help integrate the converters into your design as well as finding solutions for other aspects of your power topology…
