DC-DC converters are current and voltage regulating devices that can efficiently transfer electrical energy from one voltage source to a corresponding voltage of a different voltage level. They are often used in applications where a voltage source of a lower voltage level must be adjusted to a higher voltage level. The SUCS104805B DC-DC converter is a highly efficient, low noise, low H-shaped hybrid switched mode power supply (SMPS) with a high current output.

The SUCS104805B provides a low-power output and can be used in a wide variety of applications, including battery charging, mobile computing, and voltage regulation. Its attributes make it ideal for a wide range of applications, including industrial, automotive, medical, and consumer electronics. It is designed to provide consistent and reliable performance even under harsh environmental conditions.

The SUCS104805B has a wide input voltage range of 4.5V–13.2V, making it an ideal choice for many applications. It is also designed with a wide output voltage range of 3.3V–20V and is available in three voltage ratings. These ratings provide the user with flexibility in designing the system for optimum performance.

The main advantage of the SUCS104805B is its high power conversion efficiency. It can reach up to 95% efficiency at its maximum output power. This efficiency is achieved due to the advanced topology of the boost converter which uses better components and implements a multi-loop control system for better control and higher efficiency. It also features overvoltage protection and thermal protection.

The SUCS104805B also provides an integrated SMPS controller, which features a programmable output voltage. The integrated PWM controller can help reduce system power consumption and improve system reliability at a lower cost. The integrated controller also provides a fast transient response time for better system stability.

The working principle of the SUCS104805B is simple. The input is first rectified and filtered by a buck regulator circuit. Then, the input voltage is increased by a boost converter, which switches at a frequency determined by the output voltage. The output voltage is then monitored and adjusted by a feedback loop that regulates the PWM pulse width of the boost converter.

Finally, when the desired output voltage is reached, the boost converter stops and the output voltage is sent back to the load. With the help of the feedback loop, the boost converter can maintain the desired output voltage. Additionally, the output of the SUCS104805B is also protected during high-load operations, ensuring safe and reliable performance.

In conclusion, the SUCS104805B is a highly efficient, low noise and low H-shaped hybrid switched mode power supply. It features an integrated SMPS controller, a wide input voltage range, a wide output voltage range, and excellent power conversion efficiency. These features make it ideal for a wide variety of applications including battery charging, mobile computing, and voltage regulation.
