LM2596R-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The HTC LM2596R-5.0 is a fixed-output step-down switching regulator from the LM2596 series, manufactured by Taejin Technology. It provides a fixed 5V output with a maximum load current of 3A. The device operates at a fixed switching frequency of 150kHz and accepts input voltages up to 40V. Designed for surface-mount applications, it utilizes a TO-263-5 package (TO-263-5L) with dimensions of 10.20 x 8.60mm and a height of 4.55mm. The component supports a wide operating junction temperature range of -40°C to +125°C and features an internal thermal shutdown circuit.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number matches the required output voltage and current specifications. Confirm the package type corresponds to the intended PCB footprint. Ensure the manufacturer source aligns with quality requirements. Check for any specific handling instructions related to the surface-mount configuration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from an input voltage up to 40V. The TO-263-5 package is suitable for applications needing moderate heat dissipation without through-hole mounting. Consider the 150kHz switching frequency for standard inductor selection.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2596 family of monolithic integrated step-down DC-DC converters. The 'R' suffix indicates the surface-mount TO-263-5 package variant, distinct from the through-hole TO-220 versions. It shares functional similarities with other LM2596 variants but differs in physical form factor.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include LM2596S-5.0/NOPB and LM2596T-5.0. Verify pinout compatibility and thermal performance when replacing across different package types.
