Abstract: The invention provides a method and a device for heating an electronic component and an electronic apparatus using the method/device. A heater is disposed at the electronic component. The heating method includes following steps: driving the heater according to a duty ratio by using electrical energy of a power module. If the output voltage of the power module is greater than a first threshold, set the duty ratio as a first ratio. If the output voltage of the power module is less than a second threshold, set the duty ratio as a second ratio. If the output voltage of the power module is between the first threshold and the second threshold, adjust the duty ratio so that the difference between the output voltage of the power module and the second threshold is positively proportional to the duty ratio.
