Introduction

Modern microelectronic systems, such as products related to the internet of things, wearables, and consumer electronics, have become exceedingly complex, containing multiple cores, communications, Image signal processors, and interfaces. As a result, the power requirements of such applications have become too complicated to be handled by traditional integrated circuits. To address this issue, PMICs (Power Management ICs) have emerged as essential components for engineering reliable, efficient, and robust systems. The TPS6591102A2ZRC PMIC is specifically designed to support a multitude of power management functions required in high-end consumer products.

Application Field

The TPS6591102A2ZRC from Texas Instruments specializes in different consumer products such as mobile phones, tablets, wearables, and IoT (internet of things) connected apps, thanks to its five different input sources for a low power and high efficiency. It features a built-in Li+ battery charger up to 1.5A, enabling quick full charge of large capacity batteries with a complete control system. Its switching regulator is implemented to support a wide range of input voltage from 3.3V to 23V. In addition, it provides full-system power sequencing, enabling critical functions to be powered up or down in a reliable and safe manner.

The core operation of the PMIC is dedicated to voltage regulation. It is designed with integrated linear and switching regulators, as well as LDOs, enabling the power management design to have multiple starting points and code-free configuration. The device supports a wide range of output current, varying between 10mA up to 3A with the switching regulator, whereas its LDOs supports up to 100mA each. The integrated solution also offers a comprehensive sleep-mode system to reduce the power consumption of the system, allowing it to minimize its energy requirements when it is not active.

Working Principle

The TPS6591102A2ZRC PMIC relies on linear and switching regulators for voltage regulation. The linear regulators provide a low dropout voltage, allowing the output voltage from the regulator to closely follow the input voltage. This eliminates the need for a large number of external components, thus resulting in a simpler layout. The linear regulator provides steady output voltages from 1.25V to 5V, and with its current limit, it is possible to draw up to 300mA from each channel.(It can still draw 200mA for channels V3 and V4).

Switching regulators provide efficient and precise regulation by converting a small amount of input voltage into a higher output voltage. The operation of a switching regulator relies on a Pulse Width Modulation (PWM) control block, which converts a high-frequency carrier signal into a square wave that is controlled by a varying duty cycle. This allows the switching regulator to rapidly adjust the output voltage in response to changes in the input voltage. The switching regulator can support output voltages that range from 0.8V to 5.5V. With multiple output supplies, it is possible to achieve higher current ratings or power requirements.

Conclusion

The TPS6591102A2ZRC PMIC is a state-of-the-art power management solution for modern microelectronic systems. It features five input sources for a low power and high efficiency, built-in Li+ battery charger up to 1.5A, switching regulator with a wide range of input voltage from 3.3V to 23V, full-system power sequencing, and integrated linear and switching regulators. The switching regulator supports output voltages that range from 0.8V to 5.5V, enabling critical functions to be powered up or down in a reliable and safe manner. The PMIC provides a complete power management solution for consumer applications, making it a great choice for engineers who need reliable and efficient power management solutions.
