555 Non-TransformerDC/It2 Positive Voltage output circuit
As shown in picture9-6, 555,R1, R2 and C1 constitute an astable multi-vibrator, accordingto the following formula: f=1.44/(R1+2R2)C1 frequency of output pulse is about 8kHz, and it is output through doubler rectifier D1 and D2. If the input voltage Vin is 14V, then the output voltage ranges from 22V to 26V, the output voltage changes as load change. When load RL is 510Ω, Vo is about 22 V; when it ascends to 51kΩ, Vo is about 24V; and When RL reaches 470kΩ, Vo is about 26V.
