TPS62065QDSGRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62065QDSGRQ1 is an automotive-grade, highly efficient synchronous step-down DC/DC converter from Texas Instruments. It delivers up to 2A output current with an input voltage range of 2.9V to 6V, making it suitable for converting 5V or 3.3V system rails. Operating at a fixed 3MHz frequency, the device utilizes power save mode at light loads to maintain high efficiency and optimize low output voltage ripple. The MODE pin allows forcing fixed-frequency PWM operation for low-noise applications. It features a 2mm x 2mm WSON-8 package and supports adjustable output voltages.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (DSGRQ1) matches the required package type and tape-and-reel quantity. Confirm AEC-Q100 qualification status if automotive reliability is mandatory. Check for RoHS compliance documentation. Ensure the ordering part number aligns with the intended operating temperature range and output configuration requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 2A output current is required within a 2.9V to 6V input window. The 3MHz frequency is ideal for minimizing inductor size compared to lower-frequency alternatives. Choose the adjustable version over fixed-output variants if precise voltage tailoring is needed. Consider the Q1 designation for automotive environmental robustness.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the TPS6206x family of synchronous buck converters. It shares core architecture with non-automotive counterparts like the TPS62065 but includes enhanced testing and qualification for automotive environments. The family emphasizes high efficiency and small footprint solutions for portable and industrial applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other TPS6206x variants with compatible packages. Verify equivalent current ratings and input voltage ranges. Non-TI equivalents require careful comparison of switching frequency and thermal performance.
