Boost Converter Generates Three Analog Voltages
https://www.electronics-lab.com/boost-converter-generates-three-analog-voltages/
The standard boost converter in Figure 1 uses not only IC1, C1, L 1, D1, and C2 to generate a main 5 V output, but also additional small, low-cost components to provide two auxiliary supply rails of 10 and –5 V. These auxiliary outputs are useful for analog circuitry in small handheld instruments, which often require supply voltages greater […]
