LMR16006YQ3DDCRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LMR16006YQ3DDCRQ1 is an automotive-qualified synchronous step-down DC/DC converter from Texas Instruments. It operates with an input voltage range of 4 V to 40 V and provides a fixed 3.3 V output at up to 600 mA. The device features a high switching frequency of 2.1 MHz, enabling the use of small external components. It includes a shutdown function and maintains a low quiescent current of 28 µA. Designed for reliability in harsh environments, it supports junction temperatures from -40°C to +125°C and meets AEC-Q100 standards.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for robust performance in vehicle applications.
• High-frequency operation at 2.1 MHz allows for compact passive component selection and reduced board space.
• Integrated shutdown capability enables efficient power management by minimizing standby current consumption.

Voltage Regulators - DC DC Switching Regulators Applications

• Infotainment systems requiring stable 3.3V logic supply
• Body control modules needing automotive-rated regulation
• Sensor interface circuits in connected vehicles

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'Q3' corresponds to the required 3.3 V fixed output configuration, as other variants offer adjustable or different fixed voltages. Confirm the 'R1' suffix indicates reel packaging if bulk handling is intended. Ensure the design accounts for the SOT-23-THIN-6 package thermal characteristics under maximum load conditions within the specified automotive temperature range.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 3.3 V rail is needed for automotive electronics. Compare against adjustable versions like LMR16006YQDDCRQ1 if voltage flexibility is required. Consider the 2.1 MHz frequency trade-off between efficiency and EMI compared to lower-frequency alternatives. Ensure input voltage stays within the 4 V to 40 V limit for proper regulation.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LMR16006Y family of SIMPLE SWITCHER regulators. It shares core topology with non-automotive variants but adds rigorous qualification testing. The 'Q' prefix denotes automotive grade, while '3' specifies the 3.3 V output setting. It complements higher-current buck converters in TI's portfolio for compact power designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR16006YQDDCRQ1 offers adjustable output instead of fixed 3.3 V. LMR16006XDDCR provides 60 V input tolerance but lacks automotive qualification. LMR16006YQ5DDCTQ1 is a fixed 5 V variant. Verify pinout compatibility and thermal performance before substituting.
