LM2596HVGDP-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596HVGDP-5.0 is a monolithic integrated circuit step-down switching regulator (buck converter) manufactured by TAEJIN Technology Co. It belongs to the LM2596 series, designed for easy and convenient design of high-efficiency power supplies. The device provides a fixed positive output voltage of 5.0V and is capable of driving a 3.0A load with excellent line and load regulation. It operates with a wide input voltage range and utilizes a 150kHz fixed frequency internal oscillator. The component features thermal shutdown and current limit protection, requiring only four external components for operation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'HVGDP' corresponds to the intended package type and temperature grade as defined in the official TAEJIN datasheet. Confirm that the manufacturer designation matches TAEJIN Technology Co., distinct from other producers such as Texas Instruments or UMW who also manufacture LM2596 variants. Ensure the fixed 5.0V output version aligns with system requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output at up to 3A is required from a higher input voltage source. The LM2596HV series supports wider input voltage ranges compared to standard versions. Consider the TO-263 package for surface mount applications requiring robust thermal performance. Verify compatibility with the 150kHz switching frequency regarding external inductor selection and EMI constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part is a variant within the broader LM2596 family of SIMPLE SWITCHER power converters. While Texas Instruments originated the series, TAEJIN Technology manufactures compatible equivalents. The 'HV' designation typically indicates high-voltage input capability. The 'GDP' suffix likely denotes specific packaging or tape-and-reel configuration details unique to TAEJIN's production lines.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2596S-5.0 from Texas Instruments or LM2596HVS-5.0 from UMW, provided pinout and electrical specifications match. Verify package dimensions and thermal pad connectivity when swapping manufacturers.
