Wide operating temperature range (-40 ☌ to 125 ☌), and low output power temperature derating Excellent load regulation(integrated closed loop control) Flexible configuration, 5V/3.3V selectable output options In summary, the NIRSP31 has the following advantages: The above table compares the parameters of the NIRSP31 with those of the traditional isolated power module solution. *The parameters of the isolated power module in the preceding table are specific to a single part number, and the specifications vary with materials. Short-circuit protection / over-temperature protection / under-voltage protection Primary Secondary Parasitic Capacitance (Typ)ĭepend on the selected optical coupler / isolator Compared with the traditional isolated power module + optical coupler/digital isolator solution, it greatly reduces the PCB layout area and height, and can further reduce overall system cost. For isolated communication power supply, because its layout is relatively far away from the main power loop of the system and its power consumption is relatively low, the independent isolated power module is often preferred.With industry-leading on-chip transformer technology, the NIRSP31 integrates isolated power and three-channel digital isolators on a single chip with advanced LGA package (4mm×5mm). Whereas, the power supply solution of external transformer /multi-winding output is adopted for the isolated drive/sampling power supply due to relatively large power and concentrated layout.
Isolated power supply solution based on on-chip transformerĪccording to different requirements, the isolated power supply in the system can be divided into three parts: isolated drive power supply, isolated sampling power supply and isolated communication power supply. This article introduces the integrated isolated power 3CH digital isolated solution of NOVOSENSE, which helps developers simplify industrial system design.
As the leader of isolation technology, NOVOSENSE has been committed to exploring isolated power solutions with higher integration, reliability and cost effectiveness. In view of high voltage, safety, noise immunity and other factors in industrial system design, the demand for isolated design is more and more extensive, and transferring signal/power across isolation barrier has been one of the common challenges for designers.
