Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as TAEJIN or HTC Korea, as sourcing channels may list either entity. Confirm the specific package variant matches the required TO-220-5 form factor. Ensure the suffix indicates the adjustable version (ADJ) rather than fixed voltage options. Cross-reference the datasheet for thermal management requirements given the 3A output capability in this package type.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust, high-current buck converter is needed for industrial environments. The wide input range suits applications with varying source voltages. The TO-220-5 package facilitates heat dissipation for continuous 3A loads. Consider thermal resistance and PCB layout constraints due to the through-hole mounting style and power handling characteristics.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM4576 series of switching regulators. Variants include different packages such as TO-263-5 (LM4576R-ADJ) and SOIC (LM4576DP-ADJ). The core functionality remains consistent across the family, differing primarily in physical footprint and thermal performance. The TAEJIN branding indicates the specific manufacturer source for this component batch.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM4576R-ADJ for TO-263-5 packaging and LM4576DP-ADJ for SOIC packaging. Verify pin compatibility and thermal specifications before swapping packages. No other electrical parameter changes are expected within the same model family.
