Ericsson POL regulators are implemented by using non-isolated synchronous buck topology shown in Figure 1. During normal operation of a buck power stage, QH and QL are alternatively switched on and ...

A comprehensive understanding of switching regulator noise is important when designing a low noise switching regulator, says Leo Liu. Generally, traditional switching regulators are considered noisy ...

These days switching power supplies are nearly ubiquitous and used throughout every electronic devices. They are valued for their small size, low cost, and efficiency. However, they have the major ...
