TPS62067AQDSGRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62067AQDSGRQ1 is an automotive-grade 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, suitable for converting 5V or 3.3V rails. Operating at a fixed 3MHz frequency, it supports Power Save Mode for light-load efficiency and low ripple. The device features adjustable output voltage from 0.8V to 6V and includes an open-drain power good indicator. Packaged in an 8-pin WSON (2x2mm) with exposed pad, it operates between -40°C and +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'AQ' against official documentation to confirm exact temperature grade and quality level. Ensure the package designation matches the required footprint. Confirm AEC-Q100 compliance requirements align with target application standards before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for automotive environments requiring robust power management. The 2A current capacity suits moderate power loads. The 3MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the input voltage range covers the system's minimum and maximum rail variations.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6206x family of high-efficiency synchronous step-down converters. The Q1 suffix indicates automotive qualification, while the 'A' likely denotes a specific temperature or quality tier within that series. It shares core architecture with non-automotive variants but meets stricter automotive reliability standards.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

TPS62067DSGR is the commercial equivalent without automotive qualification. For direct functional replacement in non-critical applications, verify pin compatibility and thermal performance differences.
