Can I Adjust Power Supply with a DC-DC Converter?

This brief blog post explains how a DC-DC Converter can be used to adjust power supply in various electronic configurations.

There’s always something powering an electronic device, be it a battery or some other power source such as a circuit. The problem is, however, that power is actually not always flowing consistently. Sometimes it dips or surges. Special tools manage the situation well.

The engineers who design gear must be aware of this. It’s likely they are, though. They’ll be the first ones to suggest using AC-DC converters, a step-down AC, a step-up AC, or some other similar module. A variable power supply requires such adjustments.

For voltage adjustments, one may employ the use of a potentiometer. To adjust the output to the right level, a device may be equipped with an adjustable voltage regulator with line regulation and load regulation.

Smooth and non-pulsating high-voltage DC-DC Converters are fed into the voltage regulator, which may or may not be an LM317. Capacitors C2 and C4 then eliminate ripples in a filtering process that sits away from the regulator.

The capacitor C3 bypasses the pin of a voltage regulator to ground, to improve the ripple rejection capability. Diodes are used to protect the regulator from excess that flows through if any voltage source is connected across the output terminals of the regulator.

The adjustable high-voltage power supply is an integrated circuit that supplies the constant and controlled output voltage no matter if there are changes in input voltage.
