[DC fast charge] SY8105+IP2161 non-composite buck fast charge

• Input voltage: 6-18V (try to be greater than 13V)

• Output voltage: 5-12V adaptive

• Output current: 5A maximum

• supporting agreement:

• QC3.0 Class A, QC2.0 Class A

• Huawei FCP fast charging 5V and 9V voltage configuration

• Samsung AFC fast charging 5V and 9V voltage configuration

• Spreadtrum SFCP fast charging 5V, 9V and 12V voltage configurations

• Apple 2.4A, Samsung 2.0A, BC1.2

• Very low internal resistance of the power tube: (top/bottom): 40mΩ/26mΩ

• Ripple can be as low as 20MV (data sheet test form, 5V5A output)

• Power indicator light, changes in brightness can indirectly reflect changes in output voltage

The working current of the mobile phone when the power is 70%, the fast charge trigger fails, the reason has been identified and fixed in the engineering document: DMDP is reversed. As for the circuit, we will test it until all the functions are properly exerted. Please look forward to the test data of the new PCB!
