LMR16006YQ5DDCRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LMR16006YQ5DDCRQ1 is an automotive-qualified synchronous buck converter from Texas Instruments' SIMPLE SWITCHER family. It operates with an input voltage range of 4 V to 40 V and provides a fixed 5 V output at up to 600 mA. The device features a 2.1 MHz switching frequency, enabling the use of small external components. It includes a shutdown function and maintains a low quiescent current of 28 uA. Designed for 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 reliability certified under AEC-Q100 standards for robust performance in vehicle electronics.
• Integrated synchronous rectification within a compact SOT-23-THIN-6 package for space-constrained designs.
• High-frequency operation at 2.1 MHz minimizes passive component size while maintaining efficient power conversion.
• Low standby power consumption achieved through a 28 uA quiescent current during active operation.

Voltage Regulators - DC DC Switching Regulators Applications

• Infotainment systems requiring stable 5V rails
• Instrument clusters and dashboard displays
• Telematics control units
• Body control modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'Q5' confirms the fixed 5V output configuration, distinct from adjustable variants like 'QDD'. Ensure the 'RQ1' designation aligns with tape-and-reel packaging requirements for automated assembly lines. Cross-reference the specific revision level against the latest datasheet to confirm pinout compatibility and thermal characteristics before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5V rail is required for automotive applications with limited board space. The 600mA output current suits low-power logic or sensor interfaces rather than high-load drivers. Consider the 2.1MHz frequency trade-off between component size and electromagnetic interference. Verify that the 40V maximum input voltage covers the system's transient conditions without exceeding ratings.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LMR16006Y series, designed specifically for automotive power management. It complements other SIMPLE SWITCHER devices by offering a balance of efficiency and footprint reduction. The Q1 suffix indicates automotive qualification, distinguishing it from commercial grade parts. It serves as a key solution for 12V or 24V vehicle architectures needing regulated low-voltage supplies.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR16006YQDDCRQ1 offers adjustable output but shares the same package and electrical interface. LMR16006XDDCT is a non-automotive version with similar specifications but lacks AEC-Q100 certification. Direct substitution requires verifying temperature ranges and long-term reliability requirements match the target application.
