How should I determine the reference voltage of the error amplifier that feeds back the output voltage of a power supply IC?
- The reference voltage is the lowest voltage that can be output by a power supply IC. Hence for the power supply IC, the reference voltage should be set as low as possible. However, the lower the voltage is set, the lower will be the precision and noise immunity, and so at present standard practice is to set the reference voltage to approximately 0.7 V to 1.0 V.
