Output voltage improving circuit

Published:2011/6/23 8:56:00 Author:Christina | Keyword: Output voltage, improving

If the output voltage of the three-port fixed voltage stabilizer is lower than the needed voltage, we can use the boost circuit to improve the output voltage.The output voltage improving circuit is as shown in the figure. The R1 is connected between common ports of the output port and the voltage stabilizer, R2 is connected between common ports of the voltage stabilizer and the power supply. At this time the current of R1 is V(I1), this current gets into the R2 together with the static working current of the stabilizer. Because the static current of the stabilizer is so small (only a few mA), so when the resistance values of R1 and R2 are small, the output voltage of the circuit can be calculated from this formula:   (View)
