ip6559 scheme verification

IP6559-AC PD100W buck-boost solution verified
input voltage range: 3.6~31V (note the mos voltage resistance)
supports PD3.0, QC3.0 and other protocols, with E-mark identification output, and has been tested to activate Huawei super fast charging (22.5 w Test model Honor 20S), protocols such as 10V4A and 11V6A are still unavailable; use a PD decoy head to charge the laptop. When charging the laptop, the mos becomes hot and a bit hot.
When you need to charge the laptop, the output capacitance is recommended to be greater than 1000uf ( the
 
welder is miserable) .
 
What the chip needs to focus on is here:
the official manual gives the following instructions
, but the specific values ​​of the ground resistance of GPIO0 and GPIO1 are not given.
The current information obtained through experiments is:
1. If the AC type GPIO1 is left floating, it will only output normal Charging, no fast charge
2. When the resistance of the ground resistor of GPIO0 is 100K, the PD can output 20V. When the resistance is lower than a certain value of 100K, it can only output 12V. You can use a large enough potentiometer to test the specific amount. try
