LMZ14203 DC/DC for +V to -V application

Other Parts Discussed in Thread: LMZ14203H, LMZ14203

  Hello,

  I tried to bring up AN-2027 on this subject and the message said that it was either removed or the name has changed.  I am using the LMZ14203/LMZ14203H in a power supply design and I would like to also use it for my -V needs in this design for part commonality.  I would like to know if I can do this with a Non-Isolated module and if so what I need to be aware of to make this work reliably.  My input V is from a battery Min. +21.5V, Max. +28V.  Output -20VDC ~500mA.

  Thank You,

  Jeff
