Application Field

TPS65145PWPG4 is a multi-level power supply control IC that can be used for a variety of portable and mobile applications. It is designed to deliver multiple power rails, ranging from very low voltage ranges up to 16V. The integrated PWM controller and system controller are suitable for different types of portable systems such as battery powered consumer electronic, live broadcast equipment, digital cameras, smart phones, and tablets. In addition, its power management capabilities can be used in many appliance products such as TVs, DVD players, digital photo frames, and air conditioners.

Working Principle

The functional block diagram of TPS65145PWPG4 consists of two main blocks—one for the power supply control and the other for the system control. The power supply control block is a high-efficiency, high-performance controller. It includes voltage regulators, switchers, linear regulators, and low-dropout (LDO) regulators. With the help of these controllers, the power supply can be managed to obtain peak performance and reduce the total power consumption of the system.

The second block of TPS65145PWPG4 is the system controller. It consists of a pulse-width modulator (PWM) and a clock generator. The system controller is used to control the timing and frequency of the power control blocks. The clock generator will synchronize the output of the PWM and the input of the controllers. The system controller also includes a power management unit that enables the system to detect and manage the power requirements of different devices connected to the system.

TPS65145PWPG4 is an ideal power management solution for embedded and portable electronics. It encompasses several power management functions in a single-chip package, minimizing the use of external components. This PMIC is designed to reduce system cost and complexity while providing increased power efficiency and improved system performance.
