The signal shape at the output of IC1 and at the load remains the same, but with different amplitudes.īut when we want to use the load, that consumes more power. But it can only be used with a load that consumes no more than 0.2A. A small transistor works as a simple switch But it works much better at high frequencies.
We can use the low voltage level at the base to control the higher voltage load at the C-E, just like a relay. The simplest and most popular method is a transistor.
Because the power (P=VxI) carries only 0.02A x 10V = 0.2 watts.Īlso, we add C1 to add the efficiency of this circuit. The watt rating of R1 doesn’t need more than 0.5 watts. We can easily calculate the value of R1 by: 12V Zener Dode Regulator circuit from 22V Vin Since IC1 requires less current, a simple circuit like this is sufficient. We use a Zener diode regulator to provide a stable 12V voltage. Next step: let’s choose components according to our specified requirements, such as performance, size, and price. But it will also have a higher voltage level, from approximately 11V to 20V. The important point is that the output signal must have the same waveform as the MM5369’s signal. It is connected to the output and requires a high current.
Small transistor radio generator#
The MM5369 block is a 60 HZ pulse generator or time base.Because MM5369 requires a stable voltage power supply (12V fixed voltage). The 12V Regulator will provide a constant 12 volts when powered by 22 volts.22V DC Source is the only power source in this circuit.Block Diagram Increase voltage of MM5369 output.
It will help us visualize the circuit idea we would need. Now let’s look at the block diagram of what we want to achieve. Related Posts The concept of this circuit
