Power Management chips are helping to reduce the overall power consumption of consumer electronics. By limiting the amount of energy that is consumed, they can also help to improve the efficiency of devices. The TPS65052RSMR is a specialised Power Management chip from Texas Instruments. It provides advanced digital power regulation for modern consumer electronics, with low-loss integrated switching and wide input values. This article looks at the application fields and working principle of the TPS65052RSMR.

Application Field

The TPS65052RSMR is designed for modern consumer electronics including smartphones, tablets, and IoT devices. Its advanced digital power control allows for the reduction of overall power consumption, thus increasing the efficiency and battery life of the device. This makes it particularly suitable for energy-intensive applications such as smartphones and tablets. Moreover, as it is an ultra-small package and RoHS-compliant, it is suitable for use in ultra-compact and thin consumer electronics.

In addition, with its dual-phase architecture and wide input voltage range, the TPS65052RSMR is well-suited for applications that require support for multiple voltage rails, such as integrated voltage regulators. As such, it is also suitable for embedded systems and automotive applications, allowing for efficient and adjustable power supply in a wide range of devices and applications.

Working Principle

The TPS65052RSMR is a digital power management chip that utilises an advanced AMC (Analog Multi-mode Control) system. This system provides digital control of multiple power rails and outputs. It is a dual-phase architecture, with a total of six power phases (three for each phase). Each of these power phases is connected to its own DC/DC converter and optimised for low-loss operation.

The AMC system performs continuously, monitoring current, voltage and power usage to ensure optimum performance and efficiency. It controls each power rail individually and, when necessary, can disable one or more phases to reduce power consumption. This allows for the efficient use of energy and helps to increase the overall battery life of the device. Additionally, system-level protections are provided, such as over-current, over-voltage, under-voltage and over-temperature protection.

The TPS65052RSMR also offers 18 power rails regulation, with configurable 12-bit DAC for each one. This allows for controlled and adjustable voltages in each rail, with support for a wide range of output voltages. In addition, the chip also features integrated switching and voltage scaling FETs, offering a high integration degree, low power dissipation and low EMI.

Conclusion

The TPS65052RSMR is a power management chip from Texas Instruments, designed to provide low-loss integrated switching and wide input values. It is suitable for use in modern consumer electronics, including smartphones, tablets, embedded systems and automotive applications. The chip utilises an advanced AMC (Analog Multi-mode Control) system that provides digital control of multiple power rails and outputs. Additionally, it offers 18 power rails regulation, with configurable 12-bit DAC for each one. All these features make the TPS65052RSMR an ideal choice for power management in modern consumer electronics.
