Application Notes
- How to Evaluate the Maximum Inductor in Internal Compensation PCM Buck ConverterPDF, 2.3 Mb, File published: Sep 20, 2017
With simple frequency compensation, Peak Current Mode (PCM) control is commonly used in integratedcircuits (IC) to improve the line and load transient performance. Slope compensation is implemented toprevent sub-harmonic oscillations at a duty cycle greater than 50%. Usually the inductor is considered asa current source in a simplified PCM buck converter model, which actually has a significa
