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 ...

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 ...

In USB applications, a constant 5 V is often required. But according to the USB standard, the input voltage can vary from 4.5 to 5.25 V. So converters must be used to stabilize the voltage. However, ...

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 ...

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 ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...
