  • Linear voltage regulators for space applications
  • David, For applications where the output voltage is close to the input, the light-load efficiency of an LDO can be higher than a SMPS as there are no a.c. switching losses. Many thanks for your comment, Rajan.

  • Is your spacecraft flying reliable chips?
  • David, commercial foundries are optimised to yield high-volume die for the consumer market and many have no commercial incentive to provide long-term relaibaility data. The high-volume automotive and aeronautical markets require reliability data for the latest nodes so we need to work together with our foundry partners to share such data. If you are willing to share the fabrication technology with me (either privately or publically), I maybe able to help. Rajan.

  • I'm giving her all she's got, captain!
  • Chris, Thank you for your kind feedback: I'm aware of your company's POL and LDO and we are considering both parts. For certain light-load applications and/or where the output voltage is very close to the input voltage, LDOs can be shown to be more efficient than a switcher. Rajan.
