The TPS54110PWPRG4 is a DC-DC switching regulator from the TPS5411x family of products, released by Texas Instruments. It is designed to provide an adjustable output voltage from 1V to 6V, with an adjustable current of 0 to 1A across its input and output terminals. The device has an integrated current sink and step-up/step-down voltage regulation. It is ideal for use as a regulator in a variety of applications, including power management of portable devices, aircraft, robots and other applications.

The TPS54110PWPRG4 is the ideal device for powering digital signal processors (DSPs) and microcontrollers with low-voltage inputs. It is capable of driving small loads with both its input and output channels, resulting in high power efficiency. Additionally, the device features overvoltage protection and a thermal shutdown circuit to ensure that the output voltage remains stable.

The device utilizes a synchronous rectified buck topology to regulate the output voltage. This topology uses an internal synchronous charge pump to drive the external switch, an N-channel MOSFET, at high efficiency. The driver circuit controls the switching of the switch, allowing the output voltage to be adjusted from 1V to 6V.

The TPS54110PWPRG4 features both current and thermal feedback loop control. The current-mode loop is used to ensure that the input and output currents are within specification. The thermal feedback loop monitors the die temperature and provides over-temperature protections by reducing the current limit. This allows the device to operate at a higher efficiency over a wide temperature range.

The TPS54110PWPRG4 is an ideal regulator for applications such as battery powered systems, FPGAs, DSPs and microcontrollers. It is designed for a wide range of input voltages of up to 40V, and its low quiescent current of 17µA makes it an a energy-efficient solution. It is also designed for high power efficiency with its low output ripple and high power density.

In addition to low input and output current ratings, the TPS54110PWPRG4 has a peak current capability of 1.5A. This feature reduces the size of the input capacitor, increasing the board space savings. The device features an adjustable soft-start and soft-stop feature, which reduces startup current while maintaining output stability.

Overall, the TPS54110PWPRG4 is an efficient and reliable DC-DC switching regulator. It is suitable for a variety of applications, and its features ensure that it can provide a stable output voltage with high power efficiency. From battery powered systems, to FPGAs and DSPs, the TPS54110PWPRG4 is an excellent choice for designers looking for a high-performing regulator.
