Increase DC-DC Efficiency Across Load and Frequency

To help improve dc-dc conversion efficiency at lighter loads and higher switching frequencies, a Schottky diode can be integrated onto a MOSFET chip....

Multiphase Boost Converter Powers Car Audio Amp

Automotive audio amplifiers often use a boost converter to generate output voltages of 18 V to 28 V (or higher) from the battery...

Selecting Inductors for Low-Power Buck Regulators

Designing a buck regulator for low-power, high-frequency operations demands special attention to inductor requirements and measurement of data that's not available on the data sheet....

Low-Voltage MOSFETs Aim to Build Better Buck Converters

Power semiconductor suppliers continue to advance the state-of-the-art in power MOSFETs by enhancing their process technology...

Monolithic Regulators Migrate to Higher Voltages

Several new regulator chips are springing up to address higher-voltage and higher-power requirements for buck converters. Like their low-voltage counterparts, these monolithic regulators promise high efficiency and compact designs....

Power Chips With Magnetics Are Going Mainstream

Only a few years ago, the idea of co-packaging an inductor with a buck-converter die in a standard IC package was quite a novelty. But since Enpirion, a New Jersey-based startup, took that step in the spring of 2004, a few mainline semiconductor companies have followed suit....
