Shop Ionizer and Controls. The frequency of the square wave is voltqge by the values of R5 and C3. This rise in temperature may mostly be due to excessive external voltage, ambient temperature, or even heat sinking. The working starts with the relaxation oscillator which generates a square wave. The main reason is because the series voltxge transistor is used as a Class A power amplifier which is known for its low efficiency and power loss in the form of heat.
The functional block diagram of the IC as a switching regulator is shown below. Due to the conditions above, the same current flows through R1.
