Application Notes
- Designing Type III Compensation for Current Mode Step-Down Converters (Rev. A)PDF, 298 Kb, Revision: A, File published: Sep 15, 2010
One of the well-known benefits of current-mode control is that the system stability can be easily achieved by Type II compensation design. It is possible to improve the transient response of a current mode DC/DC converter by adopting Type III compensation to boost the crossover frequency and phase margin. Type III compensation is simple to design and needs only one extra component.
