DC-DC converters are electronic devices that convert one type of DC power to another type of DC power.  REM6-4805S/C is a DC-DC converter offered by RECOM that provides high performance and compact size for a wide variety of applications. This article will discuss the application field and working principle of REM6-4805S/C.

Applications of REM6-4805S/C include power supply circuits, LED driver circuits, and communications systems. It can be used in a variety of industrial applications such as lighting, audio, and medical equipment. The REM6-4805S/C is a highly efficient step-down converter that can provide up to 5A of output current with a wide input voltage range of 6-48V DC. The device features a low-noise, efficiency-enhanced design that operates with efficiency greater than 95%. The input-output voltage differential is regulated to a maximum of 40%. The REM6-4805S/C can also be spread-spectrum modulated, which further improves EMI performance.

The working principle of the REM6-4805S/C is similar to other DC-DC step-down converters. The device includes an integrated power switch, integrated FET, and control circuit. The control circuit regulates the output voltage by adjusting the peak current of the converter based on the reference voltage. The integrated power switch oscillates at the switching frequency to control the output voltage. When the switch is off, the inductor operates as a charger, increasing the current in the winding at the same frequency as the switch. When the switch is on, the current from the winding is returned to the output. The energy stored in the inductor creates a voltage drop when the switch is open, creating a voltage at the output that is lower than the input voltage.

The REM6-4805S/C includes a variety of protection features to ensure reliable operation. The protection features include over-voltage protection, current limit protection, and thermal shutdown. The current limit protection is designed to limit the output current and protect the device from excessive current. The thermal shutdown prevents the device from overheating in high-temperature conditions. The OVERC protection ensures that the output voltage does not exceed the rated voltage level. The device also includes a UVLO feature which ensures that the output voltage is not activated until the input voltage is high enough.

In summary, the REM6-4805S/C is a high-performance DC-DC step-down converter that can be used in a variety of applications. It features a wide input voltage range, high efficiency, low-noise operation, and a variety of protection features. The device is designed for use in power supply, LED driver, and communications systems. The working principle of the REM6-4805S/C is similar to other DC-DC step-down converters, using an integrated power switch and control circuit to regulate the output voltage. With its robust design and reliable performance, the REM6-4805S/C is an ideal choice for powering a variety of industrial applications.
