DC DC Converters

DC-DC converters are devices which convert a DC power source (a battery, rectified AC mains, etc.) to a different DC voltage level. They are used in low or intermediate DC power applications such as consumer electronics, automotive, off-grid systems, and remote telecom sites. One of the most commonly used types of DC-DC converters is the SUCS64812C-C.

Application Field

The SUCS64812C-C is typically used in solar micro-inverter applications. It converts the solar energy collected from an array of PV cells into a low-voltage, high-efficiency, DC voltage output. This type of converter is designed for use with lead-acid, lithium ion, and other types of batteries. In addition, it is also suitable for applications like motor drives, electronic instrumentation, multi-stage buck converters, and general-purpose power supplies.

Working Principle

The SUCS64812C-C is a buck-type DC-DC converter with variable output voltage. In its most basic form, the converter consists of an input capacitor, a transformer, metal-oxide semiconductor field effect transistors (MOSFETs), and an output diode. The input capacitor filters the direct current (DC) from the power supply and supplies the device with the necessary energy. The transformer then takes the input DC and transforms it into an alternating current (AC). The alternating current is then sent to the MOSFETs, which act as power switches. The MOSFETs quickly switch on and off, controlling the amount of power that is delivered to the output diode. The output diode then converts the alternating current back into a regulated DC output voltage, while the transformer reduces the voltage to the desired level. The output DC voltage can then be used for various applications.

Advantages

The main advantage of the SUCS64812C-C is that it allows for power supply noise cancellation and isolation. Additionally, due to its high efficiency, it helps reduce costs associated with using power supply components. The device also generates less electromagnetic interference (EMI) than other types of DC-DC converters, due to its concise circuit structure and design. Its power selection and flexible protection features enable it to be easily programmed and used in a wide range of applications.

Limitations

The main limitation of the SUCS64812C-C is that its output voltage range is limited to 4V-28V, making it unsuitable for applications that require higher voltages. Additionally, it can only handle currents of up to 7A, which limits its use in high-power applications. Finally, its small size makes it difficult to use in applications that require larger power supplies.Overall, the SUCS64812C-C is a reliable and efficient DC-DC converter. It is well-suited for use in a wide range of applications, including solar micro-inverters, motor drives, electronic instrumentation, and general-purpose power supplies. It helps reduce power supply noise and interference and helps increase power efficiency. However, it has its limitations, namely its limited output voltage range and small size.
