Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM22679TJE-5.0/NOPB

LM22679TJE-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22679TJE-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator featuring an integrated power switch capable of delivering up to 5A output current. It operates with an input voltage range from 4.5V to 42V and provides a fixed 5V output. The device utilizes a 500kHz switching frequency, enabling the use of compact external components. Packaged in a TO-263-7 (DPAK) surface-mount housing, it supports operation temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a high-current power switch for efficient step-down conversion
Includes internal frequency compensation and soft-start circuitry
Features thermal shutdown and cycle-by-cycle current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for industrial equipment
Power supplies for embedded computing systems
Battery-powered applications requiring stable voltage rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free composition and RoHS compliance. Confirm the TJE suffix corresponds to the TO-263-7 package variant. Ensure the -5.0 designation matches the required fixed 5V output specification for your design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V rail is needed with up to 5A capacity. The TO-263 package offers superior thermal dissipation compared to smaller footprints. Consider the 42V maximum input limit against your system's supply voltage.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22679 family of SIMPLE SWITCHER regulators. It shares topology with the LM22676 and LM22678 but differs in maximum output current ratings. The series is designed for high-efficiency DC-DC conversion in space-constrained environments.
