This is the MT3608. It is a exact copy of the famus MT3608 board.
It is a DC-DC step up adjustable boost converter. It can take input voltages as low as 2V and step up the output to as high as 28V. The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. It includes under-voltage lockout, current limiting, and thermal overload protection.
This module has a mult...

This is the MT3608 with a micro USB. It is a exact copy of the famus MT3608 board.
It is a DC-DC step up adjustable boost converter. It can take input voltages as low as 2V and step up the output to as high as 28V. You can supply electricity via micro USB. The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. It includes under-voltage lockout, current limiting,...
Single cell LiFePO4 charger (CN3058E), protector (HY2112) and 5V booster (MT3608) board with load sharing power path management.
The board was developed for 5V projects that are operated both by battery and external power. The load sharing system interrupts the connection between the battery and the load when an external power supply is connected. In this case, the project is powered by the exter...
Solar powered switch-mode charger (CN3801), protector (HY2112) and 5V booster (MT3608) for LiFePO4 batteries.
The charger provides maximum power point tracking (MPPT) and can easily be modified to work with LiPo batteries.

This circuit uses the Buck/Boost Converter circuit for typically for use in a lab bench power supply. It features both adjustable voltage AND current using potentiometers.
Without a buck/boost converter,a computer power supply can only provide a 3.3V, 5V and 12 supply lines. With the buck/boost converter created with the aid of a 555 timer, adjustable voltage is allowed. A simple transistor is us...
