Mecter introduces Mornsun's VCB_SBO-xxWR3 series of high-power-density 1/16 brick DC/DC converters, designed to support the rapid development of the 5G industry.
Two additional functions are available, selectable according to your needs. One is the VCB_SBO-xxWFR3 series, indicated by "F" in the reference, which features a heat sink design suitable for applications with higher heat dissipation requirements. The other is the VCB_SBO-xxWR3-N series, indicated by "N" in the reference, which includes negative logic control.
Uneven 5G data flow and varying usage time necessitate that telecom power supplies operate at varying loads, from light to full load. Therefore, efficiency improvements are not limited to full load but also extend to light loads.
Mornsun's VCB_SBO-R3 series utilizes frequency conversion and active clamping technology, effectively enhancing conversion efficiency under all loads. Average efficiency exceeds 90% at 10%/25%/50%/100% loads.
In practice, ambient temperatures typically range from -40℃ to +70℃ and are higher inside devices due to the heat generated by power supplies and other components. In such cases, only a power supply with a wider operating temperature range can meet actual requirements.
Mornsun's VCB_SBO-R3 series boasts a wide operating temperature range of -40℃ to +85℃ (with a full-load operating temperature of up to 50℃ and an excellent temperature reduction curve, as shown in the figure below), effectively simplifying the overall system's thermal design.
Under high efficiency conditions, losses are minimal, and device heat generation is low, significantly improving product reliability and extending its lifespan. Furthermore, the modules utilize frequency reduction technology, resulting in a no-load power consumption of only 0.48W, which can significantly reduce the system's standby power consumption.
Mornsun's VCB_SBO-R3 series, in a standard 1/16 brick format, complies with IEC/UL/EN62368 and DOSA standards. This allows users to easily replace products within the same package, eliminating the need for redesign and recertification of the PCB and reducing associated costs.
Furthermore, the circuit design incorporates input undervoltage, output overcurrent, short-circuit, and overvoltage protection, safeguarding against virtually all types of abnormal conditions and enhancing overall system reliability. A conformal coating ensures the modules are better suited to humid, dusty, or corrosive environments, improving long-term reliability in harsh industrial settings.
Applications:
It can be widely used in industrial control, electric power, instrumentation, and communication applications.
