This section provides all the equations for the control loop small signal model when the LM5157x/LM5158x is configured as a boost regulator in CCM operation. The simplified formulas allow for a quick evaluation of the control loop, but loose accuracy at high frequencies. The comprehensive formulas are more complex but provide better accuracy at high frequencies.
