One of the key challenges when designing a constant-on-time (COT) buck converter is to make it stable with low-ESR output capacitors. Although the basic theory of voltage-mode hysteric converters ...

This article provides an examination of the input capacitor requirement for single- and multiple-channel buck converter voltage regulators. The input capacitor of a buck converter is a critical power ...

Today's feature-laden portable electronics devices, typically running off a single Lithium-ion cell, often use one or more step-down DC/DC converters to power the core processor or other key functions ...

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 ...

Specify current ripple ratio to optimize a power supply , relying on extrapolation rather than intuition to choose the right off-the-shelf inductor for your application. An inductor is designed for ...

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 ...

Buck-Boost DC-DC Converters are versatile power electronic devices that facilitate the conversion of a direct current (DC) input to a DC output that may be either higher or lower than the supply ...

Diodes Incorporated has unveiled the AP61100Q, a 5.5V, 1A continuous output current, automotive-compliant, synchronous buck converter for point of load (POL) applications. With a fully integrated ...

Diodes Incorporated (Nasdaq: DIOD) today introduces four new automotive-compliant* asynchronous buck converters for 48V low-voltage rail point-of-load (PoL) applications. The AP68255Q/AP68355Q and ...

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 ...
