PMIC - Voltgae Regulators - DC DC Switching Regulators

The TPS62172DSGT is a synchronous step-down DC-DC converter designed to provide the power management needs of the microprocessor-based systems. It offers a wide input voltage (2.7V to 5.5V) and adjustable output voltage of up to 3.3V to 5.5V in hundredth\'s of a volt increments. In addition, it offers high efficiency and low output voltage ripple.

The TPS62172DSGT offers several features for improved system efficiency, including a low-voltage current-limit mode, an adjustable output voltage range, a wide input voltage range, an adjustable current-limit feature, an adjustable soft-start feature, a low-Q start feature, and power-good indication for improved system protection.

The TPS62172DSGT includes a patented low-voltage current-limit feature that allows the user to adjust the output current limit when the input voltage drops below 2.5V. This feature improves the system\'s efficiency by allowing operation up to the specified minimum output current limit at a much lower input voltage level than COT operation.

The addition of a wide input voltage range and adjustable current limit feature, as well as the adjustable soft-start feature, allows the user to optimize system performance and improve efficiency. The adjustable current limit feature provides improved protection by preventing the DC-DC converter from entering an overcurrent condition. The adjustable soft-start feature reduces the in rush current during start-up and the Q start feature prevents the output voltage from dipping below the desired level during start-up.

The TPS62172DSGT is designed to provide the low output voltage ripple and high efficiency needed for microprocessor-based systems. This synchronous step-down DC-DC converter features high efficiency opamps for both linear and pulse-width modulation, providing a smaller form factor and improved functionality.

The TPS62172DSGT offers a wide input voltage range and adjustable output voltage range which result in higher efficiency, allowing the user to optimize system performance and reduce power consumption. In addition, the adjustable output current limit and adjustable soft start features allow for improved system protection. The addition of low-voltage current-limit and power-good indication also ensure improved system protection and reliability.

Overall, the TPS62172DSGT can be used in a wide range of applications, including microprocessors, networking, communication and computer systems, non-volatile memory, and FPGAs. The adjustable output voltage range and wide input voltage range make this DC-DC converter ideal for use in applications requiring the highest level of efficiency, while the adjustable current limit feature and power-good indication ensure improved system protection and reliability.
