The TPS62240DRVR is a high efficiency and low quiescent current synchronous buck converter with integrated FETs optimized for battery-powered data transmitting and charging applications. This application field and working principle of the TPS62240DRVR should be looked at in order to understand its wide range of applications and the DC DC (direct current to direct current) voltage regulating capability it brings.This is a type of power management integrated circuit (PMIC) device and falls into the wider category of DC DC switching regulators. DC DC switching regulators convert the input voltage supplied by the batteries into an output voltage that is more suitable for the device, as well as providing a constant voltage and current.The TPS62240DRVR is primarily aimed at low power, low quiescent current applications and provides the ability to optimize system efficiency, maximize battery life and is also able to support Power Delivery (PD) profile negotiation. Also, it is able to provide high efficiencies over a wide input voltage range from 2.7V to 5.5V. Additionally, this integrated device also features an adjustable output voltage range from 0.5V to 3.6V coupled with pressure regulated outputs, allowing it to be used in many different applications. The fundamental operation of this DC DC switching regulator synchronizes the switching of the power FETs with the output voltage ripple, allowing for efficient operation and reducing electromagnetic interference (EMI). It is able to switch over 1MHz which results in very low ripple values, because of the low ripple the output voltage ripple is typically less than 1mV. Furthermore, the TPS62240DRVR is able to dynamically adjust the frequency from 100 kHz to 1 MHz based on the output load, allowing for further improvement si the system’s overall efficiency, saving power. The TPS62240DRVR is suitable for a wide range of applications and typical applications include 5V to 3V down-conversion for GNSS (Global navigating satellite system) and Bluetooth Low Energy (BLE) transmission devices, USB Type-C data transmission devices and USB-PD (power delivery) devices. It is also suitable for powering IoT (Internet of Things) chipsets, as they mostly require a nominal voltage of either 3.3V or 1.8V. In addition to this the TPS62240DRVR also has a number of features that enable it to be used in various different applications, including the ability to enable and disable the integrated power FETs using the PWRGD (Power Good) signal, allowing it to be safely used in multiple applications. It also has an enable signal, EN, that is used to enable the device and an enable signal, EN12, that controlling the action of the integrated P-channel FETs. The TPS62240DRVR is a high efficiency and low quiescent current DC DC switching regulator and is suitable for applications ranging from 5V to 3V down-conversion for GNSS transmission devices to USB Type-C power delivery devices. Its integrated power FETs ensure efficient operation and the adjustable frequency allows for improved system efficiency. Its integrated features, such as PWRGD and EN, allow it to be applied in various applications and its wide input/output voltage range make it a suitable choice for a number of different applications.
