Description

This is circuit schematic diagram of Voltage to Frequency Converter using CA3130 IC that can help you to build adjustable power supply. The main component in this circuit CA3130 IC. 

According Eleccircuit site that also published this circuit describe that this voltage to frequency converter circuit use the CA3130 OP-Amp ICs, that linearity Of changing is very well up to 0.5% and Temperature coefficient of less than 0.01% per degree Celsius.

In Figure 1, IC1 act as the frequency generator is controlled by voltage. Suppose, first the output voltage of IC1 is + 15V. C1 will be charged through D3,R4 and P1, by constant equal to (R4 + P1) C1. Until voltage at inverting input of IC1 exceeds at the non inverting input.

The voltage at non inverting pin is adjusted by resistors R1,R2 and R3. Now output of IC1 will be changed into 0 volts, and the voltage drop across at non-inverting input will be about 5 volts. Since hysteresis that cause from R3.

Now, you can read more about this Voltage to Frequency Converter using CA3130 IC circuit schematic diagram, from original source using link here.
