WEBENCH® Tools: Negative input voltage designs
Part Number: LMZ14201H
Tool/software: WEBENCH® Design Tools
The LMZ14201H (1A in Buck config) can be used in inverting configuration. The LMZ14202H (2A in Buck config) and LMZ14203H (3A in Buck config) are pin-to-pin compatible and can also be used if the current requirements in inverting demand higher current rating.
You cannot convert the -24V to -16V with this part.
What you can do is step down from +24V to +16V first with one LMZ1420xH module.
Then convert the +16V to -16V with another LMZ1420xH module.
You can use the WEBENCH tool on this page to experiment with the specifications and get a design:
and use the entry panel to enter your specifications for Buck and Inverting:
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
