Asynchronous Counter An asynchronous counter (or ripple counter) is a sequential digital circuit in which the outputs of flip-flops are connected in series, so that the output of one flip-flop serves as the clock input to the next stage. Not all flip-flops may change state at the same time as synchronous counters, so asynchronous counters are easier to design but may experience propagation delays. Table of… |

Switching Buck Regulator: Design Basics and Efficiency In electronics, a regulator is a device or mechanism which can regulate power output constantly. There are different kinds of regulators available in the power supply domain. But mainly, in the case of DC to DC conversion, there are two types of regulators available: Linear or Switching. A linear regulator regulates the output using a resistive… |

Solenoid Driver Circuit Solenoids are very commonly used actuators in many process automation systems. There are many types of solenoids. For instance, there are solenoid valves which can be used to open or close water or gas pipelines, and there are solenoid plungers which are used to produce linear motion. One very common application of a solenoid that most of us would have come across is the… |

12V to 5V Buck Converter Circuit using MC34063 In the previous tutorial, we demonstrated detailed design of Boost Converter using MC34063, where a 3.7V to 5V boost converter was designed. Here we see how to convert 12V to 5V. As we know that exact 5V batteries are not always available, and sometimes we need higher voltage and lower voltage at the same time to drive different parts of circuit, so we use higher voltage (… |
