even though your charger can provide up to 3A, it is possible that a lot of line impedance can push the voltage as seen by the charger on VBUS, to the VINDPM threshold. The default/standalone value for VINDPM is 4.76V, so it would only take 360mV of drop…

手册上是这样解释的：
If the I AV(dem) signal increases, for example in response to an AC line voltage or load change then the average output of the A1 amplifier initially decreases by the same amount. The PWM duty cycle, and inductor current, will then increase because…
