Abstract
An integrated driving module includes an oscillator, a PWM unit, a soft start controller, a first driver, and a second driver. The oscillator is connected to a voltage input end and generates an oscillating signal. The PWM unit receives the oscillating signal and generates a first driving control signal and a second driving control signal that are respectively anti-phased. The first driver outputs a first driving output signal to a first output end according to the first driving control signal. The second driver outputs the second driving output signal to a second output end according to the second driving control signal. The integrated driving module only has four connection ends for external connection to provide the two anti-phase driving output signals, such that the circuit design and connection of the primary side of the transformer is greatly simplified. The design limitation and manufacturing cost can be both lowered.
