TPS561208DDCT is a high-efficiency, 16-V input-capable, dual-phase synchronous buck regulator with advanced circuit design techniques. It comprises of two controller ICs and two power MOSFETs in one package to simultaneously provide two output voltages with very low output ripple and noiseless operation. This device is best suited for applications with tight voltage regulation, high efficiency and low noise requirements.

Applications of TPS561208DDCT

TPS561208DDCT is well suited for applications such as datacom and wireless infrastructure, automotive, cloud computing, PEM fuel cells, solar, medical imaging, and military/aerospace.

In datacom and wireless infrastructure, the device can be used in base stations as wide range input, synchronous buck converter. It provides regulated voltage outputs with high power supplies ranging from 2V to 8V dual supply. It also provides automated phase balancing which reduces the ripple on output in both phases, hence reducing the total input current and the total output noise.

In automotive, this device can be used in 12V automotive system. The regulated voltage provided by this device helps reduce electromagnetic interference (EMI) due to switching events in power distribution systems, thus providing a much quieter environment when driving the car.

In the medical imaging and military/aerospace, this device provides reliable, clean, and low noise output for sensitive systems that require a buffered input and outputs.

Working Principle of TPS561208DDCT

The working principle of the TPS561208DDCT is based on multiple switch synchronous buck converter. The device uses two controller ICs and two power MOSFETs to provide two outputs simultaneously. It has input voltage range of 4.5V to 16V and can provide output voltage of 0.6V to 8V. It also provides up to 10A of load current for each output.

The device works by first converting the input voltage using two switching MOSFETs connected in a buck configuration. The two MOSFETs operate in a 180-degree out of phase so that the output switches of each are 180-degrees out of phase with the other, thus reducing the output ripple. The two controller ICs provide separate control of both switching MOSFETs and ensure that the two outputs operate at their required voltage levels.

The TPS561208DDCT also has a number of features to improve efficiency, such as a full bridge-gate drive circuit that reduces switching losses, and an error amplifier that monitors the output voltage and adjusts the current to maintain the desired output voltage. It also has a current limit circuit that prevents damage to the components by limiting the current when the load exceeds its specified limit.

Conclusion

The TPS561208DDCT is a high-efficiency, 16-V input-capable, dual-phase synchronous buck regulator with advanced circuit design techniques. It is best suited for applications with tight voltage regulation, high efficiency and low noise requirements. Its wide input voltage range and 10A output current capability make this device suitable for many applications like datacom and wireless infrastructure, automotive, cloud computing, PEM fuel cells, solar, medical imaging, and military/aerospace.
