Good day!!
I am designing a charger circuit, in which the raw input is varying from 6V to 32VDC.
For the charger circuit to work, there is no problem since I have a DC-DC converter at the front end to ensure that the charger circuit is receiving a constant DC volt of 20V. I have tested both the DC-DC Converter & the charger circuits.
There are few requirements that need me to put few comparator circuits in my design. However, I doubt that those comparator circuits could work properly as the DC input is unstable. I need to have 5V DC for all the comparator circuits (& 2.5V reference V).
Is it CORRECT if I put the LM431 to generate the 5VDC from unstable input that varies from 6V to 32V ? or LM317 ??
Please, I need the ideas.......
