I'm using this DC-DC converter +/-5V output version and I decided to use the trim up setting to get as close to 5.5V as possible. I determined the resistor value using this formula And got around 3.33k, which gives me about +5.56V and -5.59V. However in the datasheet it has a "Voltage adjustment range" part where it has +/-10% for dual output models, which means I can get a maximum of +/-5.5V output.
- Obviously I'm getting that (and a bit over), but my question is whether meeting the maximum settings of a DC-DC converter can cause any issues?
- Are there potential problems with 'stretching' such converters?
- Would they draw more current, drain the battery faster?
Battery input is a Li-Ion 14.4V.
I need this to be around 5.5V because it goes into 2 LDOs that drop the voltage to ~5V (+/-), because as I understand, the greater the difference between intput/output for LDOs, the better their operation (?).
