DC DC Converters

DC DC converters are devices that are used to convert direct current (DC) from one voltage level to another. The SUCS1R51212C-C is one of these converters, and its application field and working principle are described below.

Application Field

The SUCS1R51212C-C is a fully digital DC to 15V/12A Synchronous Buck converter that is ideally suited for applications such as distributed power systems, battery powered systems, and cellular/wireless base station systems. It offers a very fast current transient response as well as high efficiency and long-term stability, and is an ideal solution for distributed power towards SoCs. The SUCS1R51212C-C is designed to handle input voltages from 4.5V to 15V, while output is adjustable from 0.91V to 12V within a range of 0.05V. Equipped with integrated FETs, it is capable of sinking and sourcing up to 143A of continuous current, allowing installation in any existing rack that may require a high-power load.

Working Principle

The working principle of the SUCS1R51212C-C is based on buck-boost technology. The DC power source is connected between the positive and negative terminals of the converter, and the voltage output is used to adjust an integrated PWM control circuit. This PWM circuit produces pulses that control the switching time of the power source and the load, allowing the output voltage to be regulated automatically within the desired range. During operation, two pairs of synchronized pulse width modulation (PWM) signals are generated by the controller. The first pair controls the controller, while the second pair controls the external power switch. This allows for a wide range of input and output voltage configurations, resulting in a high efficiency converter that can tolerate large changes in input voltage. The SUCS1R51212C-C also works with automatic adaptive features which can sense load variations and overclocking. It also comes with adaptive digital timeout and accurate power consumption measurement to optimize its performance in a wide variety of conditions. It also has a reliable power good indicator that shows the exact operating status.

Conclusion

The SUCS1R51212C-C is a high-power, efficient, and reliable DC DC converter that can be used for a variety of applications. Its buck-boost technology, automatic adaptive features, and power good indicator make it a reliable choice for distributed power applications.
