AC DC Converters
LS25-3.3 Application Field and Working Principle
The LS25-3.3 is a type of AC-DC converter which is designed to convert alternating current (AC) to direct current (DC). It is a highly efficient low power switching power supply which is ideal for use in a variety of applications, such as audio-visual applications, telecommunications and testing.
It is a two-stage converter which uses a MOSFET switch and an inductive element with a secondary winding. The AC input is rectified and the DC voltage is regulated by a control loop which is driven by feedback from the output voltage. The MOSFET switch is driven by a control circuit which is based on on-controller IC (integrated circuit). The input AC voltage is rectified, and then the rectified voltage is applied to the MOSFET switch. When the switch is on, current is passed to the inductor and the output voltage is regulated. The output is then rectified to a required DC output voltage.
As the name suggests, the LS25-3.3 is designed for applications which operate at 3.3V. To meet the requirements of these, it offers a regulated output within a range of 3.1 – 3.5V. The device also has low ripple, high efficiency and an inbuilt overvoltage protection.
There are several advantages to using an AC DC converter such as this, including low cost, reliability and low power consumption. The highly efficient design makes it suited for use in portable devices. Also, the overvoltage protection feature ensures that the device does not become damaged when subjected to high voltages.
The LS25-3.3 is a highly efficient and reliable AC DC converter which is ideally suited for use in a variety of applications. It is the perfect choice for those who want a compact, cost effective and reliable power supply.
