Texas Instruments\' TPS62170DSGR voltage regulator is a synchronous step-down DC-DC converters, with a maximum output current of 1.6A. Its compact 10-pin size is ideal for space-constrained applications. The TPS62170DSGR has a variety of features such as onboard output voltage and current limiting and reverse-current protection.

Application Field

The TPS62170DSGR voltage regulator can be used in a wide variety of applications, such as power supplies, motor control, current regulators, automotive, industrial and consumer electronics. It is well-suited for powering low-noise processor cores from VDD_CORE, I/O and memory buses.

The wide input voltage range of 4.5 to 17V makes it suitable for use in most power systems. It is also very efficient, with a maximum efficiency of up to 94%. This makes it well-suited for battery-powered applications, where efficiency is paramount.

The TPS62170DSGR is an ideal solution for powering embedded processors, field-programmable gate arrays (FPGAs), power-over-Ethernet (PoE) systems, as well as other high-performance, motion control and automation applications.

Working Principle

The TPS62170DSGR voltage regulator consists of a power stage, a logic stage, and a control stage. The power stage is responsible for converting the input voltage to the required output voltage, using a buck topology. The logic stage works together with the power stage to generate the feedback voltage, which is compared to the desired output voltage. The control stage is responsible for adjusting the duty cycle of the power switches, in order to achieve the desired output voltage.

The TPS62170DSGR voltage regulator is capable of providing a constant current at the output, while maintaining a stable output voltage. The output current can be adjusted by changing the resistance of the sense resistor at the output. This allows the TPS62170DSGR to be used in applications where low output ripple and smooth transition are required.

The TPS62170DSGR voltage regulator also features a low-power skip mode. This is used to reduce the power consumption when the output voltage is below a certain threshold. It also features a soft start circuit, which ensures a smooth transition when the regulator is first powered-on.

In addition, the TPS62170DSGR has an integrated MOSFET, which prevents reverse-flow current from the output to the input pins. This protects the regulator from damage caused by accidental reverse-polarity connection at the input.

Overall, the TPS62170DSGR is an ideal choice for applications requiring low power consumption, high efficiency, and stable output regulation. It provides a feature-rich and cost-effective solution for powering embedded processors, FPGAs and other high-performance, motion control and automation applications.
