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 ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

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 ...

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 ...

The synchronous buck converter is a widely used topology in low-voltage, high-current applications. One common application is a point-of-load (POL) converter that transforms a system bus voltage of 48 ...

As electronics become more advanced, the need for efficient power management increases. One crucial element of power management is the DC-DC converter, which is a device that converts DC voltage from ...
