DC DC Converters

A DC-DC converter is a device that takes in direct current (DC) and converts it to a different DC voltage. This is usually done to match the output voltage of the source to the voltage of the load. There are two main categories of DC DC converters: linear and switching. Linear converters use a series regulator that reduces the voltage to the desired voltage and outputs it as a continuous voltage. Switching converters, on the other hand, use an on-off switch in combination with an inductor or capacitor. This creates a transfer of the DC voltage from the input to the output at a higher frequency than the line frequency.

The REC3-483.3SRWZ/H2/A/SMD/CTRL is an example of a DC-DC converter. It is a non-isolated switching converter with an on/off control and a wide input voltage range of 4.5V to 17V. The output voltage can be adjusted from 0.8V to 12V with a ±0.3V accuracy. It features an external shutdown control, current and thermal limits, soft start, and built-in damage protection. The device has a high efficiency of up to 95%, and its small, low profile package makes it ideal for applications in tight spaces.

The REC3-483.3SRWZ/H2/A/SMD/CTRL is designed for a wide variety of applications. It is suitable for use in point of load (POL) regulation in networking and telecom equipment, such as servers, routers, base stations, and switches. It can also be used in automotive applications, industrial and medical systems, and power supplies of consumer electronics, such as smart phones, tablets, and cameras.

The REC3-483.3SRWZ/H2/A/SMD/CTRL has a buck-boost design, which allows it to handle input voltages both above and below the output voltage. This makes it ideal for applications where the input voltage is unknown or often changing. The device features protective functions to ensure a reliable and safe operation. Its wide input voltage range and low minimum output voltage make it suitable for use in a wide range of applications.

The REC3-483.3SRWZ/H2/A/SMD/CTRL typically works by transferring the input voltage to the output in two steps. During the first step, the on/off switch, which is controlled by pulse-width modulation (PWM), is opened and allows the inductor to store energy when the switch turns off. During the second step, the voltage is transferred to the output side through the inductor, which generates the output voltage. The closed loop circuit in the converter allows for precise and continuous voltage control.

The REC3-483.3SRWZ/H2/A/SMD/CTRL is a compact and efficient DC-DC converter that is designed for use in a wide range of applications. Its external shutdown control, current and thermal limits, and built-in damage protection provide a reliable and safe operation. Its buck-boost design makes it suitable for applications where the input voltage is unknown or often changing. Its wide input voltage range, adjustable output voltage, and high efficiency make it an ideal choice for point of load regulation in networking and telecom applications, as well as automotive, industrial, and medical systems.
