Murata Power Solutions Non-Isolated DC-DC Converter

The Murata Power Solutions Non-Isolated DC-DC Converter is used for the embedded application. It has three nominal output voltage terminals and up to 1.5A is the maximum output. Based on fixed frequency the high efficiency means very low heat and low electrical noise requiring no external component. The fixed single output converters provide both tight regulation and high efficiency directly at power usage site and are direct plug-in instead of linear regulators hence no extra outside component is required

Features and Benefits

• High efﬁciency with no external components
• No heat sink direct replacement for 3-terminal
• Operating temperature is from -40°Cto 85°C
• Outstanding thermal derating performance
• Short circuit protection
• Vertical SIP or horizontal mount, small footprint, in an encapsulated package

Applications

• Control boxes
• Control boxes
• ITE commercials
• ITE commercials

Certifications

• UL certified
