TPS56720PWP

Voltage Regulators - DC DC Switching Regulators Overview

The TPS56720PWP is a synchronous step-down DC/DC converter from Texas Instruments, designed for high-current applications. It features an input voltage range of 4.5 V to 17 V and delivers a continuous output current of 7 A. The device utilizes D-CAP2 mode control for fast transient response without requiring external compensation components. It supports adjustable switching frequencies of 500 kHz, 800 kHz, and 1200 kHz via the MODE pin. The output voltage is adjustable from 0.6 V to 13 V with ±1% accuracy. Integrated protections include overvoltage, undervoltage, overcurrent, and thermal shutdown.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the package type HTSSOP-20 and operating temperature range against specific design requirements. Confirm that the selected switching frequency configuration matches the inductor and capacitor selection guidelines provided in the official datasheet. Ensure compatibility with the required output voltage adjustment range for the target application load.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-phase solution is needed for loads up to 7 A within a 4.5 V to 17 V input window. Consider the D-CAP2 control architecture if minimizing external compensation components is a priority. Evaluate the thermal performance in the HTSSOP-20 package relative to the expected ambient temperature and PCB copper area available for heat dissipation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS56x20 family of regulators which incorporate VID (Voltage ID) capability for microprocessor core voltage regulation. Unlike standard adjustable regulators, this family allows output voltage programming via I²C-compatible interfaces in some variants, though the PWP package typically relies on external resistors for fixed or adjustable settings depending on the specific revision and configuration options available in the documentation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for TPS56720 variants with different package options such as RGCYR if board space constraints differ. Verify if TPS56520 is suitable for lower current requirements around 5 A. Ensure any substitute maintains the same input voltage range and synchronous buck topology.
