Battery-powered applications present a unique set of challenges for system designers. Optimal power delivery to the load, the preservation of battery life and the development of power management systems (PMICs) all demand careful consideration. How can we maximize the efficiency of our power systems while minimizing the complexity and cost of our designs? XC6802A42XER-G integrated PMICs provide an answer to these challenges and can be ideally employed in battery-powered applications.

The XC6802A42XER-G PMIC is a precise digital-controlled buck-boost regulator that enables precise power delivery over the wide load range needed in a variety of battery-powered applications. It delivers a high efficiency and low-ripple power at all load conditions, while providing multiple levels of protection to its internal circuits and the battery. It is well suited for applications such as medical instruments, IoT sensors, battery-powered wearables, etc.

Working Principle

The XC6802A42XER-G PMIC is based on a buck-boost topology, where an inherent advantage of delivering current from the battery to the load at the same voltage as the battery is maintained throughout the operating range. It contains built-in features specifically designed to improve system performance and reliability. For example, the PMIC supports pulse-skipping buck-boost operation to reduce ripple and reduce switching losses, as well as a dynamic energy-saving mode to reduce power consumption. Other features such as programmable peak current and overcurrent protection also help enhance user experience.

The PMIC includes input undervoltage lockout, soft start, load disconnect, and thermal shutdown, enabling connection of the battery without risk of damage. The PMIC also supports output voltage tracking and multiple output voltages, allowing the output voltage to be switched and adjusted at different power levels. In addition, it offers an integrated idle mode, which improves efficiency and reduces quiescent current and power consumption.

The XC6802A42XER-G PMIC is designed for use in applications where extreme power efficiency is a priority. The efficiency of the design is highly dependent on the input voltage, due to its buck-boost nature, but when designed properly can provide efficiencies as high as 86 percent in typical battery-powered applications. This significantly reduces power consumption and thermal savings.

In summary, the XC6802A42XER-G integrated PMIC provides system designers the ability to deliver precise and highly efficient power to their battery powered applications. Its features and capabilities enable it to be employed in a wide range of applications, and its high efficiency helps to provide greater energy savings while minimizing the complexity of the design.
