DC DC Converters : REM3-123.3S/A Application Field and Working Principle

DC-DC converters are various types of converters which are used to convert a supply of direct current (DC) from one voltage value to another. In many applications, DC supplies are required to power electronic items; however, due to fluctuating voltage levels the DC supply may not always be of the exact value required. This is where DC-DC converters come into play; they are utilized to provide a regulated DC voltage of a requested voltage level from a DC source.

REM3-123.3S/A is a custom DC-DC converter, to take a higher voltage input and adjust it precisely to a lower required voltage output (Maximum Input Voltage can be up to 20V, Output Voltage can be adjustable from 0.8V to 17V). This converter includes a wide input voltage range, high efficiency, high-rate transient response, low current ripple, and short-circuit protection. It is typically used in consumer electronic applications such as cellular phone and digital cameras, as well as other products where space or size is a concern.

Application Field of REM3-123.3S/A

The REM3-123.3S/A is a power product with very low power consumption, which usually be used in portable electronic applications where space and/or weight is a major consideration, such as mobile phones, digital cameras, tablet computers, PDAs and other DIgital Image Processing System. In addition, it is suitable for providing higher performance systems with power from a single or multiple battery sources, such as Laptop Computers, Positions, Barcode Scanners, etc. It can be also used to power Instrumentation, Military, Aerospace, Automotive, Security, and Industrial Systems.

Working Principle of REM3-123.3S/A

The REM3-123.3S/A converter utilizes a combination of Maximum Power Point Control (MPPC) and advanced pulse width modulation (PWM) technology to adjust the output voltage to the requested level from the DC source, while at the same time regulating the output current. The output current is regulated by a current-sensing feedback circuit; as the output current increases the feedback sets the duty cycle to reduce the output current. The output voltage is then adjusted using a voltage-sensing feedback circuit. This works in a similar way to the current-sensing circuit, but the duty cycle is adjusted depending on the output voltage level.

In conclusion, the REM3-123.3S/A converter is a reliable, efficient, high-quality product that can be used for a wide range of applications; it offers superior performance, with a wide input voltage range, high efficiency, high-rate transient response, low current ripple, and short-circuit protection. It is capable of providing a stable, regulated DC voltage of any desired value from a DC source, while at the same time protecting against any over-voltage or under-voltage conditions.
