Abstract: Current flowing through an inductor on a primary side of a voltage converter is sensed and compared to a threshold peak current value to determine when to end an ON portion of the voltage converter. The secondary side of the voltage converter supplies an indication of output voltage for use in determining the threshold peak current value. On start-up the primary side detects when the indication of output voltage is supplied by the secondary side across on isolation channel. Prior to detecting the indicating is being supplied, the primary side uses an increasing threshold peak current as the threshold peak current value. After detection that the indication of output voltage is being provided by the secondary side, the threshold peak current value is based on the indication of the output voltage.

Abstract translation: 检测流过电压转换器的初级侧的电感器的电流并将其与阈值峰值电流值进行比较，以确定何时结束电压转换器的导通部分。 电压转换器的次级侧提供用于确定阈值峰值电流值的输出电压的指示。 在启动时，初级侧检测输出电压的指示何时由隔离通道上的次级侧提供。 在检测到正在提供指示之前，初级侧使用增加的阈值峰值电流作为阈值峰值电流值。 在检测到二次侧提供输出电压的指示之后，阈值峰值电流值基于输出电压的指示。
