摘要: A fan controlling circuit is provided. The includes an integral unit, operational amplifier, a PMOS transistor, and NMOS transistor. unit transforms pulse width modulation (PWM) signals to voltages, transmits the voltages positive negative input terminals of amplifier. transistor coupled between first PWM signal output terminal, gate second may be formed by discrete elements use same voltage source as fans, so that design cost complexity are reduced.
