The circuit can be used to adjust voltage by TTL switch threshold. U1A and U1B form the oscillator, and its switching frequencies < 1MHz. The output of the oscillator can drive the three parallel inverters U1C, U1D U1E to provide a higher output current and output power. Its internal output transistor, L1 and D1 form a standard boost converter, when its output is low, the current only flows through the inductor L1; when the output becomes high, the energy stored in the inductor makes anode of D1 become high, D1 conduction charges for C1. The circuit and load characteristics are better than 1%, and output voltage only changes 7% in range of 0 ℃ ~ 50 ℃.
