您好,请参考下面内容:
TI does not have and likely will never have a single integrated FET charger than provide 8A and 3*4.2V = 12.6V = 100.8W. The losses in FETs will be too high, resulting in the charger IC clamping its output due to thermal regulation.
The closest…

Part Number: TPS61378-Q1 Below is the schematic that used TPS61378-Q1 as the regulator to output 5V. The input voltage is 3.3V and use an external MOSFET to switch on or off this power input.
The regulator cannot start up even with light load(0.1A).…
