LM2596HVGT-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The TAEJIN LM2596HVGT-5.0 is a monolithic integrated circuit designed for step-down switching regulator applications. It operates with a fixed 150kHz internal oscillator and supports an input voltage range up to 60V, distinguishing it from standard variants. The device provides a fixed 5.0V output and can drive a load current of up to 3.0A. It utilizes a TO-263 surface-mount package and includes built-in thermal shutdown and current limit protection features.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific manufacturer designation, as TAEJIN produces this component under license or as a compatible alternative to the original Texas Instruments design. Confirm that the TO-263 package matches your PCB footprint requirements. Ensure the 60V input rating aligns with your system's maximum voltage stress. Check for RoHS compliance status if required by your manufacturing standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this variant when the input voltage exceeds the 40V limit of standard LM2596 devices. The fixed 5.0V output eliminates the need for external feedback resistors compared to the adjustable version. Consider the thermal performance of the TO-263 package for heat dissipation in high-current applications. Verify compatibility with standard inductors and capacitors recommended for the 150kHz frequency.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2596 series of switching voltage regulators. While the standard LM2596 supports inputs up to 40V, the HV (High Voltage) variant extends this capability to 60V. The 'G' suffix typically denotes the TO-263 surface-mount package, and 'T' indicates tape-and-reel packaging. This series is widely used for its simplicity and ability to drive heavy loads with minimal external components.
