TPS659110A2ZRCR Application Field and Working Principle

The TPS659110A2ZRCR (or simply TPS659110) is a PMIC (Power Management IC) developed by Texas Instruments Incorporated. It is a specialized PMIC that includes a 3-channel LED backlight control, 3-channel DC-DC regulator, 1-channel general purpose DC-DC regulator, and 1x Sleep voltage regulator. It is uniquely designed to enable low power consumption, precise voltage tone and temperature, and to accurately detect load currents for all 3 channels of DC-DC regulators.

Application Field

TPS659110 has primary application fields that include cell phones, tablets, digital cameras, personal media players, etc. It is a highly efficient and versatile PMIC that is capable of precisely managing voltage and current levels during the operation of these devices. With its accuracy and ease of use, it is highly capable of reducing system power consumption, improving device battery life, and providing better system performance.

Working Principle

TPS659110 utilizes a built-in PMOS FET as the main switch in each of its three DC-DC channels. It works by closing the control pins of the PMOS FET and applying a high voltage to it. This voltage is then transferred to a set of coils, which then produces an output of the desired voltage from the other side of the coils. This process is repeated for each of the three channels. The three channels then combine their respective output voltages and the voltage and current conversion is complete.

TPS659110 also includes a 3-channel LED backlight control, which utilizes a set of transistors to control the power flows to each of the LEDs. The current to each LED is then adjusted by measuring the voltage drop across the transistors. This process is also repeated for each of the three channels and the voltage and current conversion is complete. With these features, TPS659110 can accurately and precisely control LED backlight brightness levels.

Conclusion

TPS659110 is a highly efficient PMIC that is capable of precisely managing voltage and current levels during the operation of electronic devices. Its unique design enables low power consumption, precise voltage tone and temperature, and accurate load current detection for all 3 channels of DC-DC regulators. With its features, TPS659110 is a great option for reducing power consumption, improving device battery life, and providing better system performance.
