LM22677TJE-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22677TJE-5.0/NOPB is a SIMPLE SWITCHER® step-down DC/DC switching regulator from Texas Instruments, housed in a TO-263-7 (DPAK) surface-mount package. It delivers a fixed 5 V output with a maximum current capability of 5 A. The device operates within an input voltage range of 4.5 V to 42 V and supports a switch frequency up to 1 MHz. It features integrated overcurrent protection and frequency synchronization capabilities, operating reliably across a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free and RoHS compliance per manufacturer specifications. Confirm the TO-263-7 package variant matches your PCB footprint requirements. Ensure input voltage does not exceed 42 V to maintain device integrity. Check for automotive qualification if deploying in AEC-Q100 environments.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output at 5 A is required from a wide input range. The TO-263-7 package offers robust thermal performance for high-current applications. Consider frequency synchronization needs for multi-rail systems to minimize audible noise or EMI interference.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22677 family of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM22679 and LM22676 but differs in specific current ratings and feature sets. The family targets efficient, compact power solutions for industrial and automotive markets.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22679TJE-5.0/NOPB offers similar functionality with potentially different thermal characteristics. LM22676TJE-5.0/NOPB provides a lower 3 A output current option. Verify pin compatibility and thermal requirements before substitution.
