Abstract: In some implementations, a microcontroller may trigger a control loop to read a feedback voltage based on an interrupt that has a periodicity based on a control loop frequency. The microcontroller may calculate a target duty cycle for a first transistor and a second transistor based on the feedback voltage. The target duty cycle may control respective proportions of time that the first transistor and the second transistor spend in an on state. The microcontroller may output, based on the target duty cycle, a first pulse-width modulation (PWM) signal to switch a state of the first transistor and a second PWM signal to switch a state of the second transistor. In some implementations, the first PWM signal and the second PWM signal may be associated with a switching frequency that differs from the control loop frequency.
