Modern electronic products have made great progress in terms of functionality, intelligence, and integration. Complex functions in one product require multiple power supply designs. To meet the requirements of small size, low cost, high efficiency and reliable power management, TPS65146RGER power management integrated circuit (PMIC) mainly supports PMIC activities.

Application Field

The TPS65146RGER is an 8-channel four-string buck voltage regulator, which provides high-performance power regulation solutions for many applications. This power management integrated circuit offers an efficient solution for applications such as phones, tablets, wearable electronics, cameras, or other end equipment.

Working Principle

The TPS65146RGER can maintain steady output voltage and the output current of each channel can reach a maximum of 2A. The input voltage range is 4.5V to 17V, and the output voltage is adjustable from 0.25V to 4.5V. It integrates one 238MHz operating frequency PWM controller that can operate up to four synchronized strings. It uses a DC-DC step-down converter to convert the input voltage into a stable output voltage. It also uses PMOSs to generate the programmable switching undervoltage lockout (UVLO). In addition, it also has a full interrupt function, which can be used to control and monitor the regions when the output voltage is too low or too high. It can also be used to monitor the short circuit, over temperature and over voltage conditions of the output voltage.

In addition, TPS65146RGER integrates the following features to simplify the design process: input power disconnect functions, low quiescent current operating modes, power supply sequencing, digital soft start functions and adjustable fixed frequency. Therefore, the TPS65146RGER can meet a wide range of power management applications.

Conclusion

In conclusion, the TPS65146RGER PMIC is an 8-channel four-string buck voltage regulator, which is widely used in many applications due to its efficiency, reliable performance and integrated features. Its multiple functions and excellent performance make it suitable for a variety of applications.
