  8. Victor Khasiev, Linear Technology Design Note 553 Introduction Data loss is a concern in telecom, industrial and automotive applications where embedded systems depend on a consistent supply of power. Sudden power interruptions can corrupt data ...
  9. Abel Raynus EDN A microcontroller requires dc operating power in the 2 to 5.5 V range, an amount that a battery or a secondary power source can easily supply. However, in certain situations, a microcontroller-based product must operate directly ...
  10. Sajjad Haidar EDN A simple blocking oscillator circuit can be used to step up voltage using properties of coil inductance ( V = L di/dt ). Such a circuit is shown in Figure 1, which is more commonly called a Joule thief. Figure 1. Basic Joule Thief ...
