Introduction to TPS62290DRVR

The TPS62290DRVR is a single-channel, PMIC, low-voltage, DC-DC switching regulator that works on a buck-boost topology. It efficiently regulates the output voltage mainly from the input voltage source, which allows a wide range of input voltage to the device. The device is the ideal choice for a power supply management solution of portable electronic products and battery-driven applications. This article introduces the application field and working principle of TPS62290DRVR.

TPS62290DRVR Applications

The TPS62290DRVR are popularly used for design in many different types of portable devices, such as laptop and Desktop PCs, smartphones, wearables, Bluetooth Audio devices, and other similar devices. Due to its high switching frequency and low-voltage operation, the device is well suited for battery-driven applications such as designed for low-power systems including USB Type-C ports and other accessories. Besides, it has a peak efficiency rate of up to 90%, and its operation range covers 2.5V to 17V, making the TPS62290DRVR an ideal device for voltage regulation and power management. Additionally, the TPS62290DRVR feature a low-standing current of 5-50µA, making it an ideal choice for power designs which require a very low current consumption when on standby mode.

TPS62290DRVR Working Principle

The TPS62290DRVR is a DC-DC switching regulator which features a buck-boost topology, allowing the input voltage to swing between positive and negative in order to achieve the desired output voltage. The device operates over an input voltage range of 2.5 to 17V with an accurate output voltage adjustable through an external resistor, which allows for a wide range of output voltage. In addition, the device has a high-frequency capacity, depending on how it is set up, the switching frequency of the device can be set to as high as 1.2MHz, enabling a decrease in external components’ size. Furthermore, the device utilizes synchronous rectifier control with 95% (minimum) peak efficiency and current-mode control, all of which contribute to a minor solution size and a low system noise. In addition, the device features soft-start, short-circuit protection, and open loop protection, which prevents any damage to the system whether it is caused by the malfunction of the device itself or the external components.The TPS62290DRVR also features integrated internal compensation, providing the user with an easy method to set up an accurate voltage regulation and increase system stability.In conclusion, the TPS62290DRVR are not only versatile and reliable, but are also cost effective and simple to use, making them a perfect solution for portable devices and battery-driven applications.
