Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number suffix corresponds to the TO-263 surface-mount package variant. Confirm manufacturer origin as TAEJIN Technology Co., Ltd. Ensure component authenticity through official distributor channels or authorized representatives. Check datasheet revisions for any updates regarding moisture sensitivity levels or pinout configurations before final integration into production designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed the 40V limit of standard LM2596 versions. The adjustable output is suitable for applications requiring non-standard voltage rails between 1.2V and 37V. Consider the 3A current capacity for moderate power loads. Ensure adequate thermal management due to power dissipation at higher input-output differentials. Verify compatibility with available standard inductor values for the 150kHz switching frequency.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2596 series of monolithic integrated circuits designed for easy and convenient design of step-down switching regulators. The HV designation indicates enhanced high-voltage input tolerance compared to standard variants. The ADJ suffix denotes the adjustable output version, allowing flexibility in setting the output voltage via external resistors. The GT suffix typically identifies the TO-263 surface-mount package type.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Cross-reference with other manufacturers' LM2596HVGT-ADJ equivalents such as those from Texas Instruments or HTC Korea. Verify pin-to-pin compatibility and electrical parameter alignment, specifically the 60V input rating and 3A output current. Ensure thermal performance characteristics match the original design requirements.
