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 ...

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 circuit described here is a 12-V dc to 5-V dc (±5%) switched-mode power supply (SMPS). The supply uses a 12-V input from an array of four 3-V dc, 40-mA solar cells connected in series. (The cells ...

This application note explains the calculation of external capacitor value for buck converter IC circuit. Change of capacitance value due to temperature can obtain stable temperature characteristic by ...

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 ...

This course introduces the basic concepts of switched-mode converter circuits for controlling and converting electrical power with high efficiency. Principles of converter circuit analysis are ...

The synchronous buck converter is the most popular topology in the PC market. The race between the top MOSFET companies is heating up with the rush to design new devices that are faster and better ...

Implementing a light load efficiency improvement algorithm, the latest synchronous DC/DC buck converters from Diodes achieve an efficiency of 96% and deliver continuous load currents of 4 and 5A, ...
