Abstract

A driving circuit and an electronic apparatus having the same are provided. The electronic apparatus includes a load circuit and the driving circuit. The driving circuit is coupled to the load circuit. The driving circuit includes a voltage-divider circuit and a converting circuit. The voltage-divider circuit is configured to receive N control signals and divides voltages of the N control signals to generate a first voltage, wherein N is an integer greater than or equal to two. The converting circuit is coupled to the voltage-divider circuit to receive the first voltage, converts the first voltage into a driving voltage, and drives the load circuit according to the driving voltage.
