Abstract
A display device and a power management chip are provided. The power management chip includes a rising-edge trigger, detecting rising edges of a pulse signal; a first counter, configured to calculate the number of the rising edges; a falling-edge trigger, detecting falling edges of the pulse signal; a second counter, configured to calculate the number of the falling edges of the pulse signal; an adder, configured to sum up the number of the rising edges and the number of the falling edges of the pulse signal; and a digital-to-analog converter, electrically connected to the adder, configured to convert to a target voltage based on the sum obtained by the adder. In such a way, the poweron time of the power management chip is reduced.
