LM2596GR-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The HTC LM2596GR-5.0 is a monolithic integrated circuit designed for step-down switching regulator applications. It operates with a fixed 5.0V output and supports a maximum load current of 3.0A. The device features an internal 150kHz oscillator, eliminating the need for external timing components. It accepts input voltages up to 40V and includes thermal shutdown and current limit protection. The component is housed in a TO-263-5 surface-mount package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin, as TAEJIN Technology produces this part under license or as a compatible source distinct from Texas Instruments. Confirm the suffix 'GR' corresponds to the specific tape-and-reel packaging variant required for your assembly line. Ensure the datasheet matches the exact electrical specifications for the 5.0V fixed version before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust 3A buck converter is needed with minimal external parts count. The fixed 5.0V output simplifies design compared to adjustable versions. Consider the TO-263-5 package for adequate thermal dissipation during high-load operations. Verify compatibility with the 150kHz switching frequency regarding inductor selection and EMI requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2596 series of SIMPLE SWITCHER power converters. The series is widely recognized for its ease of design and reliability in DC-DC conversion. The 'G' suffix typically indicates a lead-free RoHS-compliant variant, while 'R' denotes reel packaging. It serves as a direct functional replacement for legacy National Semiconductor and Texas Instruments equivalents in standard buck topologies.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible substitutes include the TI LM2596S-5.0 and UMW LM2596HVS-5.0. Verify that alternative sources maintain the same 3.0A current rating and 40V maximum input voltage limits. Check if the replacement package matches the TO-263-5 footprint to ensure mechanical fit without PCB redesign.
