  • Publication number: 20200091819
    Abstract: A solution is provided for a current balance feedback method to improve stability in a multi-phase DC-DC switching converter, where the current balance feedback signal is added to the PWM duty signal, after the PWM comparator. Using this feedback method, current balance oscillation issues caused by the non-linearity of the main control loop can be solved, and provide better current balance stability in the switching converter. Advantages include improving the stability of the current balance feedback loop by introducing the correction post PW modulation in the time domain, effectively bypassing interaction with the PW modulator. The current balance feedback loop stability improvement reduces PCB design effort and iteration.
