低噪声电源控制器及其方法

Low audible noise power supply controller and method therefor
摘要：
In one embodiment, a power supply controller of a power supply system uses an algorithm to reduce the number of drive pulses to the output transistors under light load conditions. The algorithm groups the drive pulses to the output transistors into sets and removes some of the drive pulses for each set drive pulses issued by the controller. Each successive set removes additional drive pulses.

在一个实施例中，供电系统的电源控制器使用一种算法来在轻负载条件下减少输出晶体管的驱动脉冲数。 该算法将输出晶体管的驱动脉冲组合成组，并且去除由控制器发出的每组设置的驱动脉冲的一些驱动脉冲。 每个连续的设置去除额外的驱动脉冲。
