Hi team,
I have to make a project based on LM331 (F-to-V converter) and the microcontroller LPC1769.
From the 5V - USB pin of the micro I have to power all the electronics devices:
-LM331 to 5V or 4.5V
-I have to choose an ADC and power it to the convenient voltage.
- I have to choose an EEPROM and power it to the convenient voltage.
As I know, the USB output from a common PC offers a voltage from 4.4 to 5.25, so I was thinking in a Buck/Boost converter but I'm afraid of the noise.
Do you think it's a good idea to use a LDO (after the Buck/Boost) to power the ADC? The noise from the DC-DC converter will be critical for some part of the circuit? Any suggestion for a good Buck/Boost converter?
Thank you.
