DC DC converters are used in a variety of applications, from aircraft to consumer electronics. The REC5-4812DRWZ/H2/C/M/SMD-R is one of the many types of DC converters frequently used. This section provides an overview of the REC5-4812DRWZ/H2/C/M/SMD-R and its application field and working principle.

Application Field and Working Principle

The REC5-4812DRWZ/H2/C/M/SMD-R is a DC-DC adjustable buck converter with an operating frequency of 1.5 MHz and a power range of 5 – 48V. It has a wide range of application in various fields, such as consumer electronics, automotive, industrial, medical, and telecom. This type of DC-DC converter is also compatible with most electronic devices like laptops, tablets, smartphones, etc.

The REC5-4812DRWZ/H2/C/M/SMD-R works by taking a constant input voltage and outputting a variable voltage through its integrated current-mode buck converter. This power-conversion technique is also known as a “dc-to-dc buck-boost converter”. The converter can be adjusted to buck or boost an input voltage to a different output voltage.

The REC5-4812DRWZ/H2/C/M/SMD-R regulator consists of two separate power devices, a synchronous rectifier and the output voltage regulation amplifier. The synchronous rectifier, also termed an active switch, is a power transistor that is connected between a high-side voltage source and the output voltage. The rectifier is responsible for the primary conversion of incoming voltage. The output voltage regulation amplifier is a complex internal circuitry that controls the output voltage of the device. This circuitry regulates the output voltage as it adjusts the voltage difference between the drain and gate terminals of the synchronous rectifier.

The device also comes with additional features like soft-start, output current monitoring, thermal protection, and input under/over voltage protection. The soft-start feature prevents the output voltage from rising too quickly, thus avoiding inrush current. This feature is especially useful in high inrush-current applications, such as motor drives. The output current monitoring allows for the detection of overcurrent/short circuit conditions. The thermal-protection feature prevents the device from over-heating during high-power operations. The input under/over voltage protection prevents the converter from operating outside its operational range.

The REC5-4812DRWZ/H2/C/M/SMD-R DC DC converter is a versatile, adjustable buck converter with a wide range of applications. Its features such as over-current protection and thermal-protection, make it a reliable and safe choice for operating a variety of devices. With its features, the converter is capable of delivering stable, adjustable, and energy efficient power conversion.
