Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the manufacturer designation corresponds to TAEJIN Technology Co., as the LM2596 architecture is widely licensed across multiple semiconductor vendors. Confirm the suffix 'GR' aligns with the specific package type and tape-and-reel configuration required for your assembly process. Ensure the part number explicitly denotes the 3.3V fixed output variant to distinguish it from adjustable or other voltage versions in the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required at up to 3.0A with minimal external component count. The 150kHz switching frequency allows for smaller filter inductors compared to lower-frequency alternatives. Verify that the input voltage range supports the HV (High Voltage) specification if operating above standard limits. Ensure the application environment does not exceed the thermal shutdown thresholds defined in the datasheet.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM2596 series represents a family of simple switcher power converters originally popularized by National Semiconductor. TAEJIN Technology produces variants under license, maintaining the core functionality of the original design. The LM2596HVGR-3.3 specifically targets applications requiring a robust, low-cost buck converter solution with fixed voltage regulation, suitable for general-purpose power management in consumer and industrial electronics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2596T-3.3 and LM2596S-3.3 from Texas Instruments, provided pin compatibility and thermal performance are verified. Other manufacturers such as HTC Korea and ON Semiconductor offer equivalent parts within the LM2596 family. Cross-reference the specific suffix codes to ensure identical packaging and electrical tolerances before substitution.
