Many of today’s switching power supplies implement synchronous rectifiers to improve efficiency. In isolated topologies, the power-supply controller typically is located on the primary side of the ...

Lack of coordination between asynchronous resets and synchronous logic clocks leads to intermittent failures on power up. In this series of articles, we discuss the requirements and challenges of ...

When semiconductor companies cite chip performance levels, the immediate follow-up question is increasingly, "But at what power consumption?" The performance/power efficiency debate is picking up as ...

Power supply circuits come in the form of voltage step-up (boost) or the more common step-down (buck) DC/DC converter. Many of today’s applications require multiple voltage rails to drive a variety of ...

CMOS is, and will continue to be, the work-horse process technology of the semi-conductor industry. But designers of large devices, of complex SoCs and of devices using multiple IP elements are ...

The IR3621M and IR3621F from International Rectifier are voltage-mode, dual-output bi-phase synchronous buck controller-driver ICs for high performance point-of-load (POL) buck converters used in ...

There is one thing that unites almost every computer and logic circuit commonly used in the hardware hacking and experimentation arena. No matter what its age, speed, or internal configuration, ...
