A DC power supply is one that supplies a constant DC voltage and current to its load. Depending on its design, a DC power supply may be powered from a DC source or from an AC source such as the power mains.
There are two main designs for the DC power supply: Linear DC Power Supply and Switching DC Power Supply (also known as Switch Mode Power Supply). This page contains the details of Lingfran switching power supply.
Switching DC power supplies were first introduced in the late 1970's, today they are the most popular form of DC power supplies in the market due to their exceptional power efficiency and great overall performance. Lingfran Switching DC power supply regulates the output voltage through a process called pulse width modulation (PWM). The PWM process generates some high frequency noise, but enables the switching power supplies to be built with very high power efficiency and small form factor. Lingfran switching power supply with a good design and can have excellent load and line regulation.
