TPS60131PWPRG4 Application Field and Working Principle

The TPS60131PWPRG4 is an inductor-based DC-DC, switching regulator designed by Texas Instruments. It is a PMIC, Voltage Regulator, DC DC Switching Regulator, which incorporates an N-channel power MOSFET to provide a fully integrated, single-stage solution for portable devices. The TPS60131PWPRG4 approach provides better stability, electrical noise performance, and lower overall cost compared to other regulator topologies.

The TPS60131PWPRG4 is available in both single-supply and dual-supply versions. The single-supply version is designed to operate from a single input power source and can deliver up to 10 A of output current. The dual-supply version is designed to operate from two input power sources, typically the battery and a wall adapter, and can deliver up to 20 A of output current.

The TPS60131PWPRG4 offers a variety of features that make it well suited for a wide range of applications, including portable, high-performance computing, wearables, and consumer electronics. The device is designed to deliver high efficiency, low standby current, and small form-factor solutions.

Working Principle

The TPS60131PWPRG4 is a DC-DC switch mode regulator designed to convert input voltages in the range of 1.5 V to 5.5 V to output voltages in the range of 0.6 V to 3.6 V. It uses an internal N-channel power MOSFET to provide high-efficiency switching and features a peak current mode control scheme to provide tight regulation and fast transient response.

The device includes several protection features, including an input undervoltage lockout (UVLO) to prevent under-voltage conditions, an overcurrent protection (OCP) to prevent overload conditions, and thermal shutdown (TSD) to protect the device from overheating. Additionally, the TPS60131PwPRG4 includes a programmable soft-start circuit to prevent inrush current during startup.

The TPS60131PWPRG4 offers excellent line and load regulation and provides very low output ripple across the entire operating range of 1.5V to 5.5V. The device is capable of handling output currents up to 10A when powered from a single supply, or up to 20A when powered from two supplies. The device has an adjustable switching frequency that can be set between 1 MHz and 1.3 MHz and is capable of handling up to 20V at the input.

Conclusion

The TPS60131PWPRG4 is an inductive DC-DC switch mode regulator designed to provide an efficient, cost-effective solution for converting input voltages in the range of 1.5 V to 5.5 V to output voltages in the range of 0.6 V to 3.6 V. It offers excellent line and load regulation, low output ripple, and integrated protection features, making it an ideal choice for a variety of applications.
