The move to step-down converters using higher switching frequencies has generated another problem for system designers however. If it isn't filtered, DC/DC converter input ripple and noise can reach ...

A voltage-mode hysteric constant-on-time (COT) buck converter turns on for a fixed time when the output voltage is less than its reference voltage, enabling fast transient response and requiring ...

This engineering essentials on buck converter efficiency presents the relevant equations needed to estimate power losses in the converter. Following the equations, which are presented ...

Benefits of using a two-phase buck converter include ripple voltage reduction, fewer input capacitors, and better efficiency.

As a capacitor's characteristics depart from the ideal, designing for minimum input ripple voltage and current also becomes more important to extend capacitor lifetimes and supply reliability. In this ...

Some voltage ripple is an inherent feature of the buck converter design, but it’s inversely proportional to output capacitance, so most designs include a few smoothing capacitors on the output side.

Technical Terms Buck-Boost Converter: A type of DC-DC converter capable of both stepping down (buck) and stepping up (boost) the input voltage while maintaining the same polarity.

The three-level buck converter topology enabled by the new IC delivers exceptional efficiency and significantly reduces the required inductance for regulating the output voltage. Its innovative design ...

Both buck converters have wide input voltage ranges—with the AP62500 covering 4.5V to 18V, and the AP62800 covering 4.5V to 17V (making both suitable for 5V and 12V rail applications).
