Power management integrated circuits (PMICs) are devices that provide a power solution for mobile devices, consumer, commercial and industrial applications. Specialized PMICs have been developed to optimize power management for processes that require specific capabilities. MAX17117ETJ+ is one of these specialized devices. It is a high-efficiency, 180-kHz, high-voltage buck converter with low-quiescent current and integrated soft start, enabling optimal efficiency maximum power delivery to the load from an input voltage source, such as battery.

The MAX17117ETJ+ is designed to enable a synapse powered programmable microcontroller (PMIC) to manage the power of its system. It is capable of operating with input voltage sources up to 10 V, providing the maximum efficiency possible in applications using the PMIC. The MAX17117ETJ+ is also designed to provide current foldback in the case of an overcurrent event or during start-up, protecting the load from damage.

The MAX17117ETJ+ operates through a dedicated current sensing MOSFET, which accepts an input voltage and provides an output voltage at the lowest possible noise level. The MAX17117ETJ+ also provides a dedicated active discharge MOSFET, which ensures rapid discharge of the output voltage during shutdown.

To improve system performance, the MAX17117ETJ+ incorporates several regulated features. Users can select a fixed output frequency of 250 kHz or 350 kHz, allowing for optimal efficiency. The device also provides up to four fixed output voltage levels which can be adjusted by the external sense resistor. Similarly, the adjustable output voltage can also be regulated with external resistors. A single input pin can be used to set the output voltage of the device, as well as to enable or disable it.

To improve efficiency at light loads, the MAX17117ETJ+ integrates an active discharge MOSFET with fast discharge time, eliminating the need for a large output capacitor to ensure rapid discharge of the output voltage. The high-efficiency integrated MOSFET also resolves the issue of drain-source resistance. Additionally, the low-quiescent current and low-noise operation of the device provide the ultimate performance when compared to traditional power management solutions.

With its advanced features, the MAX17117ETJ+ is ideal for powering a wide range of applications. It is frequently used in advanced metering systems, automotive systems, communications equipment, renewable energy systems, and other industrial applications. It is especially useful in advanced metering systems, due to its low-quiescent current and fast current limiting features.

In conclusion, MAX17117ETJ+ is an ideal choice for a specialized PMIC solution, particularly for use in advanced metering systems, automotive systems, communications equipment, renewable energy systems, and other industrial applications. It provides an efficient, high-performance and cost-effective solution for PMIC power management.
