This voltage to frequency converter circuit has an oscillator that is voltage controlled and has a small, 0.5% deviation. IC1 function as a multivibrator and produces rectangular impulses with equal ...

MC34161 includes a reference power supply which delivers 2.54V at pin 1. The signal level applied at pin 2 is internally compared with a 1.27V voltage. D5 zener diode, togheter with R1 and C4 provide ...

Is it possible for a tiny microcontroller to run on a massive 48-V battery? This DIY electronics project makes it happen with ...

The series will explore various topologies of Switched Mode Power Supplies. In this first part, the focus is on general voltage converter circuits, including AC to AC and AC to DC converters.

By manipulating the switching frequency and turns ratios of the transformer, the circuit can have an arbitrary output voltage. In this case, it is designed to take 220V AC and convert it to 8V DC.

A decent stepdown converter usually achieves an output-voltage ripple of less than 2% (40 mV in our case). For a 560-µF output capacitance, Eq. 5 yields 18.8 mΩ for the maximum calculated ESR.
