When adjusting phase compensation, if the resistor at the ITH pin is set to the recommended value and the capacitance of the capacitor is increased until anomalous oscillations cease, then the value deviates considerably from the recommended value. In this case, is it better to also adjust the resistance value?
- To deal with this situation, the resistance is reduced, but ordinarily, operation is essentially stable at or near the value recommended by the data sheet. The inductor value and output capacitor value should also be checked to ensure that they are not greatly different from the recommended values. If operation is not stable for components near the recommended values, some other factors may be involved, including the layout.
