In many applications, the system’s input voltage supply can be unstable or vary over a wide range. Because most loads in today’s electronic equipment are sensitive and require tightly regulated voltages, a regulator is often used to convert and stabilize the source voltage. For many years, the prevailing means to achieve this regulation has been to use Linear Regulators. Though inexpensive, Linear Regulators are highly inefficient, leading to issues such as high power loss and temperature rise due to efficiency levels in the range of 40% ~ 60%. Using a switching topology, CUI’s Switching Regulators are able to achieve the same results in a much more efficient manner.
