LM2576SX-5.0/J7001717

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576SX-5.0/J7001717 is a SIMPLE SWITCHER® series monolithic step-down switching regulator manufactured by Texas Instruments. It provides a fixed 5V output with a maximum load current of 3A. The device operates from an input voltage range of 4V to 40V and utilizes a buck topology. Key electrical specifications include a typical switching frequency of 52kHz, a maximum duty cycle of 100%, and a quiescent current of 5mA. It supports operation over an extended temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix J7001717 against official Texas Instruments documentation to confirm it denotes a specific tape-and-reel packaging variant or distributor-specific marking rather than a functional deviation. Ensure the source document explicitly links this suffix to the standard LM2576SX-5.0 electrical characteristics before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required with up to 3A load capability and an input voltage up to 40V. The TO-263 package offers thermal advantages for surface-mount applications. Consider the 52kHz switching frequency for balancing component size and efficiency in space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576HV series of SIMPLE SWITCHER regulators. It shares core architecture with other variants like the LM2576SX-ADJ but differs in fixed output voltage configuration. The J7001717 suffix typically indicates specific manufacturing or packaging details handled by authorized distributors or secondary markets.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements include LM2576SX-5.0/NOPB and LM2576HVSX-5.0/NOPB from Texas Instruments. Verify pinout compatibility and thermal performance requirements when substituting.
