This circuit is designed using two IC's -one is NE 555 which is wired to an astable multivibrator that operates at 100Hz frequency and the second one is CD4013 which is a CMOS dual D-Flip flop. Above all for MT3608 to start working, the EN pin should be tied to high. The circuit is similar to 12V to 5V converter using BJT transistor but its much more stable, efficient, and higher current output (around 5A or even higher). An SMPS is perhaps the only way to go but even then it will be of the order 80-90% efficient so perhaps 2W to dissipate, perhaps less if you are careful in the . If the answer is the later, then just run your 5V 1000Hz signal to the base of a transistor and tie the collector up to+12 (level shifter) Or, if the 12V needs to source & sink significant power, you could run your 5V 1000Hz signal to the control diode of a solid state relay that will output your 12V at the same rate (since 1000Hz is slow . 2N3904 Transistor (Collector) connect to one end of Multimeter. 12v to 5v 2a converter circuit diagram.

The circuit uses an n-channel MOSFET to convert the low voltage logic level to a high voltage logic level. Working of 12V to 5V Circuit. The same design can be used for boosting a 3.7V to 24V from a Li-Ion cell. The very center of the circuit is undoubtedly an oscillator, created close to a . This circuit is basically a step-up DC-DC converter, which permits to acquire 15 volts of output originating from an ordinary 1.5 volt (B1) battery without necessitating the use transformers or customized integrated circuits. You will get about 9.1V at the output. If you convert the 4V to 12V then the 12V has less than 0.1W (inefficiency of maybe 80%) so 0.08W at 12V allows a maximum output current of only .08W/12V= 6.7mA which will not run a motor. The 7805 totally works in heat dissipation of the extra energy it receives to reduce the voltage, so it may not be ideal but gets the job done for most cases. You can use an NPN transistor (and base resistor) to change your output to an open-collector output. 5. We use IC No: LM2577 ADJ. Connect the circuit as given in the circuit diagram properly.
