LM2596HVGR-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596HVGR-5.0 is a monolithic integrated circuit step-down switching regulator manufactured by TAEJIN Technology Co. It belongs to the LM2596 series, designed for easy and convenient design of buck converters. The device is capable of driving a 3.0A load with excellent line and load regulation. It features a fixed output voltage of 5.0V and operates with a wide input voltage range. The internal oscillator runs at a fixed frequency of 150kHz, allowing the use of smaller filter components compared to lower-frequency regulators.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Fixed 5.0V output version available within the adjustable series
• Capable of driving a 3.0A load with high efficiency
• Includes thermal shutdown and current limit protection
• Requires only four external components for operation

Voltage Regulators - DC DC Switching Regulators Applications

• Simple high-efficiency step-down (buck) regulator
• Efficient pre-regulator for linear regulators
• On-card switching regulators
• Power supply for battery chargers

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the component is sourced from TAEJIN Technology Co., as the LM2596 part number is widely used across multiple manufacturers including Texas Instruments and National Semiconductor. Confirm the suffix 'GR' corresponds to the specific package and tape-and-reel configuration intended for your assembly process. Ensure the datasheet matches the 5.0V fixed output specification rather than the adjustable variant.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.0V output is required from a higher input voltage source up to the maximum rated input. The 150kHz switching frequency allows for compact passive component selection. Consider the thermal performance requirements for continuous 3.0A loads, as the device relies on external layout and heatsinking for thermal management under heavy load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component is part of the LM2596 family of simple switcher power converters. While originally popularized by National Semiconductor and later Texas Instruments, TAEJIN Technology produces compatible versions. The 'HV' designation typically indicates a High Voltage input capability variant within the broader LM2596 ecosystem, suitable for industrial and automotive applications requiring robust input ranges.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2596S-5.0/NOPB from Texas Instruments or LM2596T-5.0 from other manufacturers. Verify pinout compatibility and thermal pad connections before substitution, as package variations exist between TO-220 and TO-263 formats.
