TPS76815QPWPREP Application Field and Working Principle

The TPS76815QPWPREP is a voltage regulator with an integrated low-dropout (LDO) regulator, which offers up to 15 A of adjustable current path in a wide variety of applications. It platform is suitable for many high current applications such as automotive lighting, cellular base stations, and FPGA, DSP and other high-current DSP applications. It provides the flexibility to output adjustable selector voltages between 0.9 and 7.0 V with a user-programmable output voltage accuracy of ±3 mV.

The TPS76815QPWPREP is typically used in PMIC - Voltage Regulators - Linear applications. It features a very low IQ current at no load condition of 190 nA, a high PSRR that eliminates the need for additional external filters, and a low output noise (<1 mV RMS). The device supports a wide range of input sources, including DC sources of 1.2 to 7 V, and also supports 12 V and wide input ranges of 0.9 to 7 V. The integrated advanced-level protection circuit protect the device from over current, overvoltage, and thermal overload protection, and also prevents reverse loading.

Working Principles of the TPS76815QPWPREP

The working principle of the TPS76815QPWPREP can be described as follows. It accepts DC input sources of 1.2 to 7 V and wide input ranges of 0.9 to 7 V, and uses an advanced-level protection circuit to protect the device from over current, overvoltage, and thermal overload protection. The device also includes a low-dropout (LDO) voltage regulator IC with an adjustable selectable range of 0.9 to 7.0 V and a user-programmable output voltage accuracy of ±3 mV. It provides a very low IQ current of 190 nA at no load condition and a high PSRR that eliminates the need for additional external filters. The device is also able to reduce output noise (<1 mV RMS) with its integrated advanced level of protection.

The TPS76815QPWPREP also has adjustable current paths of up to 15 A, meaning that the output current is adjustable from 0 A to 15 A. This makes the device suitable for many high current applications such as automotive lighting, cellular base stations, and FPGA, DSP and other high-current DSP applications. This flexibility also allows for power savings, as the output current is adjusted according to the required power level.

The TPS76815QPWPREP also has an adjustable shutdown mode, a soft start capability, and a current limit of 15 A. The adjustable shutdown mode allows the device to be powered off in 1.25 mV steps, while the soft start functionality ensures a smooth transition between the power down and up states. These features make the TPS76815QPWPREP a versatile and reliable voltage regulator.
