R-78B9.0-2.0 Frequently Asked Questions (FAQs)

  • RECOM recommends a PCB layout with a large copper area connected to the tab of the R-78B9.0-2.0, and a thermal via connecting the top and bottom layers to dissipate heat efficiently.
  • While the R-78B9.0-2.0 is rated for operation up to 85°C, RECOM recommends derating the output current at high temperatures to ensure reliable operation. Consult the datasheet for derating curves.
  • RECOM recommends following proper PCB design and layout practices, such as using a solid ground plane, minimizing loop areas, and using shielding if necessary, to ensure EMC compliance.
  • RECOM recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, depending on the input voltage and output current requirements, to ensure stable operation.
  • Yes, but RECOM recommends using a dedicated current-sharing circuit or resistors to ensure equal current distribution among the paralleled devices.
