Use ne555 to make DC-DC boost circuit
Source: InternetPublisher:elleny Keywords: Boost circuit ne555 DCDC Updated: 2023/11/28
This circuit can achieve DC boost output and does not require a transformer. The 555 integrated circuit and R1, R2 and C1 form an astable multivibrator. According to the resistance and capacitance parameters in the figure, the oscillation frequency is about 5kHz. It is rectified by VD1 and VD2 and the voltage is doubled for output. If the input voltage VCC=12V, the output voltage is about 20V~24V, which varies depending on the load.
