The TPS65140RGER offers unmatched power management to enable highly efficient portable designs up to 7 W. It is an integrated power management device (PMIC) with Analog Control and Sequencing. This article will focus on the application field and working principle of the TPS65140RGER.

Application Field for TPS65140RGER

The TPS65140RGER is designed specifically to support applications that require multiple independent power rails and require high efficiency. Typical applications include mobile phones, tablets, portable medical devices, IoT devices, and other highly compact electronic products.

The device includes two low-voltage high-efficiency buck converters, two low-dropout (LDO) regulators, a dedicated battery charger, a precise analog control chipset, and intelligent sequencing capability.

Working Principle of TPS65140RGER

The TPS65140RGER uses multiple power stages to achieve high-efficiency power delivery. The main power supply (VIN) is first regulated by a high-efficiency buck converter to produce the main output voltage (VOUT). This main output voltage is then regulated by two low-dropout (LDO) regulators to provide the necessary independent switchable rail voltages. The battery charger section provides accurate charging current and voltage regulation.

The core of the TPS65140RGER is its precise analog control chipset. The chipset provides a variety of features to adjust the switching regulation and to optimize the efficiency at various load levels. It also provides an effective method for simplifying the design process and reducing the external components.

The device includes an intelligent sequencing feature which automatically controls the power-on and power-off sequencing of the output voltages. This feature can be used to minimize power supply noise and ensure system reliability. It can also be used to reduce startup time and improve system performance.

The TPS65140RGER is an ideal solution for energy-efficient, high-efficiency, low-noise power management in space-constrained applications. It provides a cost-effective solution and a great value for designers looking to streamline their design process and reduce system power requirements.
