Modern digital products are more and more complicated, the higher performance requirements of the products, and the various functions that need to be supported, the power supply system is becoming more and more complex. In response to the trend of diversified digital product development, Texas Instruments (TI) launched the TPS53317ARGBT special purpose voltage regulator. It is different from traditional adjustable or fixed DC-DC converters, and supports high performance and superior flexibility solutions. It can be applied in many high-end ID product applications and cost-sensitive products. By introducing the application fields and working principle of TPS53317ARGBT, this article provides some references for the development of industrial products. TPS53317ARGBT Applications

The TPS53317ARGBT is a high-efficiency, compact, multiphase interleaved synchronous buck converter. It is designed for applications that require multiple voltage outputs and can work together with up to 4-phase node to provide wide-range solutions. It has a wide input voltage range from 3V to 14V, easy configuration, excellent MOSFET driving, and a variety of voltage readback methods. It is ideal for data centers, telecom, flash memory arrays and high power density application solutions. Furthermore, the amount of light and fan noise can be reduced by using TPS53317ARGBT, making products thinner and quieter.

The TPS53317ARGBT can achieve up to 95% efficiency, which is beneficial in reducing the design cost. With TI\'s innovative FlexFET™ low-side power MOSFET technology, it can reduce switching losses, significantly improve power conversion efficiency and power density. Besides, it supports very short response times and a wide variety of motion detection algorithms. Its switching frequency can be adjusted between 200KHz and 2.2MHz, making it compatible with many different applications. Overall, TPS53317ARGBT is capable for providing high efficiency, small size and low noise application fields.

The TPS53317ARGBT is a two-stage synchronous buck regulator that combines a 4-phase interleaving controller and an analog PWM (APW) controller. The first converter is used to regulate the output voltage, while the second converter is used to regulate the peak current. The TPS53317ARGBT has a wide range of features, which include differential sensing, short-circuit protections, dynamic voltage scaling, and current/power limitation. It also provides a current/power limiter circuit, as well as fault protections that are adjustable.

The 4-phase interleaving controller synchronizes the switching signal of the 4 power stages based on a single clock signal. Then, the 4 signals are combined together to form a 4-phase interleaving signal. This signal will then be fed to the upper MOSFETs to drive the load. Furthermore, the fault protection circuits built into the TPS53317ARGBT monitor the current and temperature of the system, and provide protection if abnormal conditions occur.

The APW controllers constantly monitor the output voltage, and control the voltage ripple. This allows the device to maintain a stable voltage output and minimize the impact of core noise on audio and video applications. In addition, the integrated voltage and current feed-forward topology allows the TPS53317ARGBT to accurately detect the input voltage and current of the system, and provide a complete fault detection and protection system.

The TPS53317ARGBT is a versatile voltage regulator that is suitable for many forms of digital products. Its highly efficient power control structure helps reduce system costs and power consumption, while applying a robust fault detection and protection system. It can be used in many fields of ID product applications, such as data centers, telecom, flash memory arrays and other high power density solutions. Therefore, TPS53317ARGBT is a great solution for those who are developing industrial products.
