DC DC Converters

DC to DC converters are a type of electric circuit used to transform the voltage level of a source up or down, allowing compatibility between different types of electrical devices. This technology is used in a wide range of applications, from smartphones and tablets to electronic vehicles and medical equipment. One of the most advanced types of DC to DC converters is the SUW60515B, which is used in various scenarios across multiple fields.

Overview

The SUW60515B is a synchronous buck DC to DC converter from Texas Instruments, designed for high efficiency, wide input, and high power applications. It is based on a single-stage, buck-boost architecture, with a fast transient response, excellent thermal performance, and high efficiency. This device is suitable for use in automotive ECU, NVMe-SSDs, drones, medical equipment, microservers, and other high power applications. It is designed to work with input voltages from 6V to 38V and output voltages from 0.6V to 17.5V, with an adjustable switching frequency from 500kHz to 3MHz. It is also capable of handling up to 15A of output current, and comes with an integrated bypass controller for protection, and a wide operating temperature range of -40°C to 125°C.

Working Principle

The SUW60515B operates on a single-stage, buck-boost architecture to provide maximum efficiency and flexibility. The architecture consists of two step-down (buck) and two step-up (boost) stages, allowing it to produce a wide output voltage range ranging from 0.6V to 17.5V. The device is also designed to work on wide input voltage ranges, from 6V to 38V.The device is based on a synchronous switching architecture, where the switchers are discharged prior to the switching process. This allows for faster switching, allowing the device to reach up to 3MHz. The integrated bypass controller allows for protection against shoot-through current, over-temperature and over-current conditions.

Applications

The SUW60515B is well suited for use in a variety of applications, including automotive ECU, drones, medical equipment, microservers, and other high power applications. Its wide input voltage range and fast transient response make it ideal for automotive applications, while its high efficiency and excellent thermal performance make it a great choice for medical applications. Its adjustable frequency also makes it well suited for applications such as drones and microservers, which require a fast switching frequency.

Conclusion

The SUW60515B is a high-efficiency, wide input, and high-power DC to DC converter. Its single-stage, buck-boost architecture, fast transient response, excellent thermal performance, and adjustable frequency make it well suited for a variety of applications, ranging from automotive ECU to medical equipment and drones. With its reliable performance and wide range of features, the SUW60515B is sure to be a valuable addition to any project.
