It offers excellent controllability and robust thermal performance, as well as high reliability.

The TPS2114APW is designed for point-of-load (POL) and point-of-use (POU) power conversion applications. Its wide input voltage range, from 2.7 V to 5.5 V, makes it suitable for a wide range of systems, from wearable technology to system-on-module applications. Furthermore, it can provide up to 0.8 A of current, enabling it to power a wide range of device types. It is also highly integrated, and has various protections, such as over-current, over-voltage, and under-voltage protection, making it ideal for robust system designs.

Working Principle of TPS2114APW

The TPS2114APW is a synchronous buck PMIC, which means it uses a power MOSFET to control the power conversion process. As input voltage and load current changes, the TPS2114APW adjusts the duty cycle of the power MOSFET, to keep the output voltage constant. This provides a wide range of applications and allows for excellent output voltage accuracy. In addition, the device features a low quiescent current of only 10 μA, making it ideal for low-power applications.

The TPS2114APW utilizes a peak current-mode microstepping approach to provide dynamic load transient response. This technology allows for fast control loop that helps deliver flexibility, control, and high efficiency in a wide range of designs. Additionally, the device features a fixed frequency current mode architecture, which allows for excellent EMI performance in systems.
