3.1 Error Amplifier

The error amplifier in this chip has a significant impact on what can be done with the feedback loop. To get a realistic model, assume that the error amplifier has 80 dB (dc) gain, with a 2-MHz GBWP. This may be a bit conservative, but ensures a stable loop if designed with these constraints.
