Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM22677QTJE-5.0/NOPB

LM22677QTJE-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22677QTJE-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER® step-down DC/DC switching regulator designed for automotive and industrial applications. It integrates a 5A power switch and operates from an input voltage range of 4.5V to 42V, delivering a fixed 5.0V output. The device supports a switching frequency up to 1MHz with synchronization capability. It features AEC-Q100 qualification for automotive use, operating reliably within a temperature range of -40°C to +125°C. The component utilizes a TO-263-7 (DPAK) surface-mount package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated 5A power switch for high-current step-down conversion
Frequency synchronization capability for noise reduction in multi-rail systems
Automotive-grade AEC-Q100 qualification for reliability
Built-in overcurrent protection and thermal shutdown

Voltage Regulators - DC DC Switching Regulators Applications

Automotive infotainment and body control modules
Industrial point-of-load regulation
Distributed power supply architectures
Battery-powered equipment requiring efficient voltage stepping

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'QTJE' confirms automotive grade (Q) and tape-and-reel packaging (JE). Ensure the '5.0' indicates the fixed 5V output variant. Confirm NOPB denotes lead-free/RoHS compliance. Cross-reference the manufacturer datasheet revision date against your design requirements to ensure feature consistency.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5V output at 5A is required from a 4.5V to 42V input source. The synchronous buck topology offers higher efficiency compared to non-synchronous alternatives. Consider the TO-263-7 package for its thermal performance and ease of PCB mounting in space-constrained automotive or industrial enclosures.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM22677 family of SIMPLE SWITCHER regulators. The family includes variants with adjustable outputs and different current ratings. The LM22677 specifically targets applications needing robust 5A performance with integrated protection features, distinguishing it from lower-current counterparts like the LM22670.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM22677 variants with compatible pinouts and electrical characteristics. Verify that any replacement maintains the same output voltage, current rating, and automotive qualification status if applicable.
