Voltage converter circuit using TDA 2003
6 to 12 volts Converter Circuit using TDA 2003Two IC TDA2003 are used here, which are connected to oscillators and their results are identical, but 180 out of phase. Capacitors C3 and C6 determine the frequency of these oscillators respectively. When IC1's output charges capacitor C1 to the voltage across diode D2. When the output of IC1 is high, this voltage is also added to the C1. Now the
