All,
I'm looking to use a boost converter https://www.onsemi.com/pub_link/Collateral/CAT4238-D.PDF to drive my LCD display.(Manufacturer = Densitron 84-0102-000). I've never used a boost converter before and was a little confused on the voltage output. What determines it? The forward voltage drop of the LCD/LED is 28V from it's datasheet. The datasheet(for the boost conv) goes into great detail on the current which makes sense but it only gives a range for the voltage output which is up to 36 volts. It appears that this device is a constant current source so depending on what impedance you hook up to this will change the voltage output but the current will always be what you set it up to?
If anyone can help me make sense of this part it would be appreciated.
Thanks.
