- MT3608 is not switching for particular input voltage
MT3608 wrong output voltage but the former hasn't shown how far the capacitor had been placed in the beginning (is my cap C4 placed too far or acceptable?) and after he found the solution, and the latter seems to be not resolved, only hints
- current - MT3608 gets very hot only handle 1A - Electrical Engineering . . .
The MT3608 datasheet only shows output current up to 1A at 5V, and you may need a similar boost ratio as the 3V to 5V curve shown (where efficiency is heading downhill fast at 1A) Therefore, despite being rated for 2A, under these conditions I think 1A is a more realistic maximum
- Alternate Inductor that can be used for MT3608 boost converter circuit
2 I am planning to use MT3608 schematic for my project to boost the voltage from 3 7V to 5V I am planning on making a customized PCB with all the requirements that are needed for the project In the MT3608 module, which is available mostly in the outside market, the inductor used is 22uH
- Raspberry Pi UPS with 18650 + TP4056 + MT3608
In theory, it should provide 5v (output of the MT3608) when powered either from USB wall charger or from 18650 battery (through the TP4056) The Mosfet will do the switching between mains and battery
- dc dc converter - MT3608 Improper Output Voltage - Electrical . . .
Here's the peculiar part; If I use an external DC power supply and connect it to the output of the MT3608 and then raise the MT3608's output to 5V and then disconnected the external 5V source the circuit will happily maintain 5V until I cycle power Does anybody have any ideas? Two things worth mentioning:
- switch mode power supply - MT3608 output voltage changing with input . . .
The MT3608 is a boost converter (step-up), as you rightly mentioned A boost converter increases the input voltage to a higher level, and you cannot have the input voltage higher than the output
- Charging 2S (8. 4V) Lithium battery using MT3608 5V- gt;8. 4V DC-DC with . . .
I am thinking of using this chain: 5V from USB -> MT3608 Step Up converter tuned to 8 4-8 5V -> 2S 8 4V BMS or balancing circuit -> 8 4V Lipo battery Normally there also should be something like a specialized "charger" like TP4056 (for 4 2V) or TP5100 (for 8 4V)
- MT3608 DC-DC converters in parallel with common output
I'm thinking to use two DC-DC MT3608 converters in parallel with a single potentiometer Has anyone experience with these converters?, Any advice? Thanks
