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 ...

For those living before the invention of the transistor, the modern world must appear almost magical. Computers are everywhere now and are much more reliable, but there are other less obvious changes ...

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 ...

Synchronous buck converters have received great attention in low power, low voltage DC-DC converter applications in recent years due to their high efficiency. International Rectifier Inc. has ...

TU Delft researchers found that smart PV modules with integrated buck converters can significantly improve energy yields under partial shading by allowing individual substrings to operate ...

Nonisolated DC/DC step-down voltage conversion is almost exclusively based on the ubiquitous buck regulator topology. The multiphase buck regulator has inherent advantages over its single-phase ...

The design equations developed for the buck converter in Chapter 3 are a subset of a general set of equations that are applicable to a great variety of DC-DC converters. These types of converters are ...

Diodes has announced four automotive buck converters for 48V rail point-of-load use. The parts are similar, but rated at 5 to 100V or 5 to 80Vin, and 2.5A or 3.5A out. There are not synchronous ...

Increasingly, many industrial PCs (IPCs), USB power delivery (PD), and automotive digital video recorders (DVRs) require wide V IN DC/DC converters to cope with a wide range of battery voltage ...

Learn how a bootstrapped buck-boost converter can be used to extend the battery life of a low-cost, portable LED lamp.
