Regulated outputs shut down despite being within nominal range?

2024-07-11 01:31:51 The maximum output power of OUT1/USB OUT, OUT2 and OUT3 are 5V*1.5A+3.3V*1A+12V*0.5A=16.8W. If the module is only power by the battery, the maximum output power is determined by the battery 3A over current threshold. Take the battery voltage as 3.7V and an average 85% efficiency. The maximum output power of the module will not exceed 3.7V*3A*85%=9.4W (when the battery is fully charged, the battery voltage can reach 4.2V, max output power turns out to be 10.7W) . When total the output power exceed this value (though OUT1-OUT3 are still within their nominal value), the battery protection IC will take it as over current error and cut off the connection between battery and the regulated outputs. To push the regulated outputs to its limit, use the USB or SOLAR IN to externally power the module. Tonny12138
