Voltage Regulators - DC DC Switching Regulators datasheet and documents for LMR51460SQDRRRQ1

LMR51460SQDRRRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LMR51460SQDRRRQ1 is an automotive-grade synchronous buck converter from Texas Instruments. It supports input voltages from 3V to 36V and delivers up to 5A of output current. The device features a wide switching frequency range of 200kHz to 2.2MHz, enabling the use of small external components. It operates within a junction temperature range of -40°C to +150°C and includes integrated bootstrap diodes and a low quiescent current of 600nA for efficient standby operation.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated bootstrap diode eliminates the need for an external high-voltage Schottky diode, simplifying the bill of materials.
Wide switching frequency range allows optimization between efficiency and component size for various design requirements.
Automotive qualification ensures reliability and performance in harsh vehicle environments with extended temperature capabilities.

Voltage Regulators - DC DC Switching Regulators Applications

Automotive infotainment systems
Digital cockpit power distribution
ADAS sensor power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package and tape/reel specifications. Confirm that the specific revision matches your design requirements. Cross-reference with authorized distributors to validate authenticity and traceability for automotive compliance.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing automotive DC-DC converters requiring high integration and robust thermal performance. The built-in bootstrap diode reduces external component count compared to similar controllers. Ensure the application voltage stays within the 36V maximum limit and consider the 5A continuous current capability for load requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LMR514xx-Q1 family of Simple Switcher® power modules designed for automotive applications. It shares architectural similarities with other members like the LMR51425 but offers higher current capacity. The family focuses on reducing solution size through high-frequency operation and internal integration of critical power stage elements.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LMR514xx-Q1 variants such as LMR51425SQDRRRQ1 or LMR51410SQDRRRQ1 if lower current is acceptable. For non-automotive equivalents, check the commercial LMR51460 series, though automotive qualification must be verified separately.
