The circuit adjusts the voltage by controlling TTL switching threshold. U1A and U1B form the oscillator andtheoscillator'sswitching frequency is less than 1MHz. Output of oscillator drives three parallel inverters U1C, U1D and U1E. They can provide higher output current and output power. The internal output transistor, L1 and D1 form a standard boost converter. When the output is low, the current only flows through the inductor L1. When the output is higher, the energy stored in the inductor forces the anode of D1 to become higher. C1 conducts to charge D1.
