TheTPS75115QPWPRG4 smart buck-boost linear regulator is main utilized in space-limited applications. It is an ideal option for regulating the voltage output in mobile or handheld applications and also offers improved efficiency, which is beneficial when running on battery or DC power. In this article, we shall discuss the application field and working principle of the TPS75115QPWPRG4.

The TPS75115QPWPRG4 is a step-up/step-down linear voltage regulator that can provide a wide adjustable output in the range of 0.6V to 5.5V. This makes it usable in a variety of applications that require an adjustable output voltage. The device is a highly cost-effective alternative to DC-DC converters when a simple solution is required without sacrificing the performance needed for the mobile application. In addition, its integrated switching MOSFET enables greater load current and supply voltage compared to many DC-DC solutions.

The device can also operate with a power supply up to 17V and includes a selectable battery backup system. Its internal power management reduces current consumption to extend battery life and its adjustable power saving mode reduces power consumption further by reducing the output current. This makes it possible to use the TPS75115QPWPRG4 in space-constrained mobile applications, enabling the device to maximize the benefits of a regulated voltage while reducing total bill of material costs.

The TPS75115QPWPRG4 has its own integrated 0.2Ω PMOS FET switch that controls the voltage output. In buck mode, current is fed to the circuit via the external inductor and the output voltage is regulated by the internal control loop. In the boost mode, current is drawn directly from the output to the circuit and the voltage is controlled by the on-board MOSFET switch. Additionally, the TPS75115QPWPRG4 includes an adjustable soft-start function with low current consumption which ensures smooth start-up and avoids inrush current.

The TPS75115QPWPRG4 also includes terminals for control, shutdown and heartbeat monitoring. In the shutdown mode, the device is completely disabled and the output voltage is reduced to 0.6V, resulting in a current consumption of less than 10µA, ensuring that no power is wasted. The TPS75115QPWPRG4 also features an adjustable high-frequency, low-noise oscillator with a programmable range of 500kHz to 2MHz. This ensures a smooth output voltage transition and further maximizes its efficiency.

In summary, the TPS75115QPWPRG4 is a cost-effective and highly efficient smart buck-boost linear regulator that can be utilized in space-limited mobile or handheld applications. It offers a wide output voltage range of 0.6V to 5.5V, integrated PMOS FET switching, adjustable soft-start function and low-noise and high-frequency oscillator. Its integrated power management functions also ensure that the device will offer a longer battery life and power savings in addition to improved efficiency.
