DC-DC Convertors

DC-DC converter is widely used in modern power electronics system, especially in the requirements of the highest efficiency and low noise environment. The LES50A48-1V2RE is an example of this type of converter, which converts an input DC voltage to the desired output voltage and current characteristics efficiently and reliably. This article will discuss the application fields and working principle of LES50A48-1V2RE.

Application Fields of LES50A48-1V2RE

LES50A48-1V2RE is suitable for a variety of power supply applications, such as industrial control systems, instrumentation, military applications, communications, and more. It is suitable for current ranging from 0.5A to 10A, while its maximum power range is up to 40.5. The wide range of input voltage requires AC input voltage of 85VAC~277VAC, and DC input voltage of 18V~75V, allowing it a wide range of applications.

Working Principle of LES50A48-1V2RE

DC-DC converters operate on the principle of converting direct current into alternating current and then back into direct current. The LES50A48-1V2RE employs a Synchronous Buck converter topology to do this efficiently and reliably. The switch hard drives the inductor while the diode provides the path for the recirculating current. Two output capacitors, C1 and C2, are used to minimize output noise and limit the output ripple voltage. In addition, it also utilizes a P-channel power MOSFET on its primary side, while the secondary side has an N-channel power MOSFET driving a synchronous rectifier diode.

The LES50A48-1V2RE offers high efficiency, wide voltage input range, and a flexible switching frequency that can reach up to 3 MHz. It supports soft-start, short-circuit protection/over temperature protection, and over voltage and over current protection, so that it can be used in a reliable and safe manner. With its high efficiency, the LES50A48-1V2RE is more energy efficient and environment friendly than many other DC-DC converters.

Summary

The LES50A48-1V2RE is a DC-DC converter that employs a synchronous buck converter topology for converting an input DC voltage to the desired output. It offers a wide variety of input voltages and current ranging from 0.5A to 10A, making it suitable for various power supply applications.
