Abstract
Embodiments herein provide a device for calibrating a voltage driven by a PWM signal for a circuit board. The device includes a controller configured to generate the PWM signal according to a PWM duty cycle value, and a voltage regulator configured to generate an output voltage according to the PWM signal. The controller is further configured to calibrate a relationship between the PWM duty cycle value and the output voltage based on a plurality of configured PWM duty cycle values and a plurality of corresponding voltages measured from the voltage regulator, and drive the circuit board by configuring the PWM duty cycle value based on the calibrated relationship.
