CS5207-2GT3 Application Field and Working Principle

CS5207-2GT3 is a high performance integrated device that provides two regulated linear outputs for low voltage/low power applications. It is designed for use with two power domain systems, allowing for both a higher performance computation domain and a lower power I/Os domain. The device integrates two controller ICs, two linear power regulators, and two voltage reference outputs to generate two regulated output voltages, while providing superior power efficiency.

Application Field

The CS5207-2GT3 is well suited for applications with both high performance computing requirements and low power I/Os requirements. It is particularly well suited for applications in embedded consumer electronics, mobile devices, and medical applications. It also offers superior performance when combined with a unique power saving feature.

Working Principle

At its core, the CS5207-2GT3 uses dual rail control topology managed by two independent control ICs that manipulate two linear voltage regulator outputs into the required regulated output voltages. The two control ICs support both low range and high range input voltage and allow for two widely adjustable output voltages by simple resistor selection. The two power regulators deliver two different voltage levels, allowing for higher performance and lower power consumption.

Each regulator has its own reference voltage and separate control circuit. The two separate control circuits can be programmed to provide different output levels, enabling the device to adapt to different needs and also performing under-voltage and over-voltage protection for both outputs. This provides excellent robustness and reliability to the device. The two voltage references provide very high accuracy and current sharing. Additionally, the CS5207-2GT3 is designed to get rid of typical high frequency noises and offers superior EMI performance.

The device can also provide power saving features, such as power up and down, as well as fast voltage ramping on either control IC. This makes it suitable for applications that require dynamic power saving and faster response times.

Conclusion

The CS5207-2GT3 is an ideal solution for embedded consumer electronics, mobile devices, and medical applications. It offers two independent linear voltage regulator outputs, coupled with excellent power efficiency and fast voltage ramping capabilities. Additionally, the two integrated control ICs provide superior accuracy and reliability, as well as power saving features.
