The PMP7935 is a single-phase synchronous buck converter module rated for 0.9V output at 45A from an input voltage of 12V. It is used for CPU core power in an enterprise network switching application.

Integrating both a 36 V fast buck and linear regulator, the LTM8028 µModule®regulator from Linear Technology produces a low noise, digitally programmable, regulated output voltage (Fig. 1). Fig. 1.

So-called “conventional wisdom” sometimes takes a long time to change and recognize new realities. Among the many common beliefs is that switching regulators are relatively “high noise” devices, while ...

Some 99 percent of the “design” problems associated with linear and switching regulators can be traced directly to the improper use of capacitors: wrong type, wrong value, or incorrect physical ...
