About Switching Power
Switching power supply covers many areas. Embedded engineers have to take a lot of care when working with switching power supplies because there are a lot of factors at play.
Changing just one parameter can set in chain a butterfly effect until finally you don’t have the power supply that you started off with. It is one of the reasons they are hesitant to tamper with power supplies.
It doesn’t help that switching power supplies are a popular alternative; in some cases, even necessary for DC-DC power supply. Nevertheless, standard power supplies are still used in a majority of DC loads.
But on the other hand, most of them don’t match the special power requirements of motors, LEDs, microprocessors and other types of loads, where the source voltage is unregulated. One example of this is battery operated devices.
Custom power supplies may be a better option in this case. Modern SMPS units are quite versatile and they are available for specific output voltages. There are many SMPS circuit configurations.
Like this, manufacturers can reduce the design burden on common power supplies, also enhancing the versatility of the devices that can be used with such power supplies.
Another advantage of SMPS power supplies they are much more efficient in converting power than common power supplies.
