Power management integrated circuits (PMICs) are a type of integrated circuit (IC) which are used to supply reliable and efficient power to different circuits within a system. In particular, PMICs with DC-DC switching regulators can be used to control the conversion of a DC input voltage to a DC output voltage, allowing the power supply to be efficiently adjusted depending on the situation. The MAX759EWE+T is a voltage regulator designed for applications such as processors, memory, and other integrated circuits. This article will discuss the application field and working principle of the MAX759EWE+T.

Applications

The MAX759EWE+T is ideal for use in a wide range of applications. One of the primary uses is in systems which require a reliable, high-efficiency power supply. The MAX759EWE+T can effectively convert an input source, such as a 12V battery or a wall adapter, into a DC output voltage of either 3.3V or 5V. This allows for the power supply to be finely adjusted depending on the needs of the system.

The MAX759EWE+T voltage regulator can also be used in embedded systems which require high performance. For instance, the MAX759EWE+T can be used in applications such as processors, memory, and other integrated circuits. It can also be used to supply power to DSL modems and Ethernet routers, as well as other digital audio/video devices. Moreover, it is perfect for applications where high-efficiency and low noise levels are required.

Working Principles

The MAX759EWE+T voltage regulator is based on a DC-DC switching regulator, which is a type of switching converter that uses two energy storage elements (MOSFETs) for voltage conversion. The MAX759EWE+T operates at a switching frequency of 300 kHz, allowing for a high conversion efficiency with low EMI. The output voltage is regulated via an internal voltage reference, which is adjusted with an external voltage divider.

The MAX759EWE+T features both differential and single-ended outputs, allowing for flexibility in the type of output required. The device also has an output current setting circuit, which allows for the output current to be adjusted depending on the application. In addition, the MAX759EWE+T is protected against reverse polarity and short-circuit conditions.

Conclusion

The MAX759EWE+T is an ideal DC-DC switching regulator for use in high-efficiency, low-noise embedded applications. With its adjustable output voltage configuration, high conversion efficiency, and high switching frequency, the MAX759EWE+T is the ideal voltage regulator for a range of applications, such as processors, memory, and digital video/audio devices.
