Traditional power-supply design practices place much emphasis on the selection and placement of the output capacitor to meet tight ripple and noise requirements. Customers are willing to spend money ...

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 ...

In the conventional dc-dc converter buck topology (Fig. 1), power from the input voltage source is transferred to the output filter by turning on the pass transistor. When the pass transistor is on, ...

1. Converter circuit is 157 mm3 including two chip inductors. The basic series capacitor buck converter shown in Fig. 4 harnesses the hybrid switched capacitor/inductor approach. It uniquely combines ...

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 ...

Texas Instruments has introduced an IC to mediate between a power rail, a load and a back-up supercapacitor. All the time sufficient voltage is available at the input, the input is connected directly ...

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 ...

Analogue Devices has combined switched capacitor and inductive buck conversion in the same topology to reduce the size of step-down dc-dc converters. Called LTC7821, this is “industry first hybrid ...
