In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

This application note talks about the design of a simple DC-DC converter. Buck converter works similarly to a step down transformer. Buck converter steps down the voltage input into a lower voltage ...

Another lifetime ago, and as a young engineer, I had to design a power conversion system. The input power came as raw electrical energy from a jet engine during flight. The output power was input to ...

Buck converters, a pivotal class of DC–DC converters, are widely implemented in modern power electronics to achieve efficient voltage step-down conversion. Recent advancements focus on enhancing ...

Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

HB (high-brightness) LEDs require a large amount of current to operate. When driving HB LEDs from a voltage source, you can set the required current with a suitable series resistor. If the voltage ...

As electronic products have grown in complexity with highly evolved feature sets, system designers by necessity have developed correspondingly sophisticated schemes for load and power management.

Buck converters are a critical element in modern power management, providing efficient voltage step‐down in a wide range of systems from battery-operated devices to industrial applications. Their ...

Field sensor transmitters in industrial automation, process control, actuator control, and building automation applications are used to measure temperature, pressure, flow, level, displacement, and ...

Designing a circuit is a lot easier on paper, where components have well-defined values, or lacking that, at least well-defined tolerances. Unfortunately, even keeping percentage tolerances in mind ...
