B.4 Common Error Amplifier Compensation Designs
There are four guidelines that should be kept in mind when designing the error
amplifier compensation. If reasonably followed, they will yield a good compen-
sation design.
1. The closed-loop phase should be kept less than -300 degrees whenever
the gain is greater than 0dB.
2. The closed-loop gain cross-over frequency should be as high as practically
possible. This quickens the transient response time of the supply.
3. The closed-loop gain at dc should be as high as possible. This has a direct
bearing on the output load regulation of the supply.
4. The resulting average slope of the closed-loop gain curve ...
