Introduction

The TPS2814PWR is a monolithic, high efficiency, non-isolated, isolated, or two-output, non-isolated, isolated power supply with a power management integrated circuit (PMIC). It is a low-voltage, low-cost and high-efficiency solution for power management in a variety of end applications. This PMIC is designed to interface with a variety of integrated circuits (ICs), such as processors and microcontrollers, to provide advanced power management and protection.

Applications

TPS2814PWR is suitable for a variety of end applications which require reliable and efficient power conversion. It can be utilized in portable devices, such as smartphones, tablets, laptops and other mobile gadgets, as well as some industrial equipment, including automated gates, door bells and access control systems. Furthermore, it is suitable for automotive, medical and military applications, where a reliable and efficient power solution is needed.

Features

TPS2814PWR has a wide range of features for efficient power management. Its maximum output power is up to 28W and maximum efficiency up to 91%. It provides two output voltages of up to 24V and can be operated from an input voltage range from 6V to 28V. It has built-in protection including thermal shutdown, overvoltage protection, undervoltage protection, current over-limit protection, and short-circuit protection with single-wire communication interface.

Functional Description

TPS2814PWR integrates a wide variety of power components, such as a linear regulator, an LDO, a buck regulator, and a dual power management integrated circuit (PMIC). It provides a wide range of output voltages and currents depending on the application. The buck regulator provides a high-efficiency, switching converter with output power up to 3W, while the linear regulator provides a low-noise and low-distortion power for sensitive applications. The LDO and PMIC are suitable for low-power non-isolated and isolated two-outputs applications.

working principle

TPS2814PWR uses the buck converter and linear regulator components to provide high-efficiency and low-noise power conversion. The power from the input power source is first stepped down by the buck converter and then to a desired state and polarity by the linear regulator. The LDO and PMIC provide a two-output voltage that is electronically adjustable, thus providing precisely regulated low-voltage output. The dual PMIC then provides a single-wire communication interface to monitor the operating temperature and output voltage and current, as well as to control the operating temperature and voltage on the two outputs.

Conclusion

The TPS2814PWR is a low-cost, high-efficiency and low-voltage PMIC designed to provide reliable and efficient power conversion in a variety of end applications. It integrates a buck regulator, a linear regulator, an LDO, and a dual PMIC to provide a wide range of output voltages and currents. It also provides numerous protection features, such as thermal shutdown, overvoltage protection, undervoltage protection, current over-limit protection and short-circuit protection. With its wide range of features and protection, it is a well-suited gate driver for many applications.
