The 555 DC raising pressure circuit

Published:2011/6/3 2:15:00 Author:nelly | Keyword: DC, raising pressure | From:SeekIC

As shown on the figure 9-11, the astable multi-oscillation consists of the 555,R1 and C1. The oscillation frequency depends on the time constant of R1 and C1. The frequency shown on the figure is about 20kHz. The output voltage is about 2.2 times higher than the input DC voltage by dual voltage rectified. The load current can reach 50mA. It uses the bipolar 555.
