How to Properly Terminate an unused OP-Amp to Avoid Noise and Power Related Issues An op-amp plays a very crucial role when it comes to designing circuits with analogue components. But while implementing such op-amp based circuits, there are situations where one or more op-amps are left unused, this causes undesirable behaviour in one or all of those unused op-amps thus impacting total system performance. To avoid this type of… |

High Power High Efficiency Buck Converter Circuit using TL494 A buck converter circuit (step-down converter) is a DC-to-DC switching converter that steps down voltage while maintaining a constant power balance. The main feature of a buck converter is efficiency, which means that with a buck converter on board, we can expect extended battery life, reduced heat, smaller size, and improved efficiency. We previously made a few simple Buck… |
