Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2596SX-12

LM2596SX-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596SX-12 is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator in a TO-263 (D²PAK) surface-mount package. It provides a fixed 12V output with a maximum load current of 3A. The device operates from an input voltage range of 4.5V to 40V at a fixed switching frequency of 150kHz. Key electrical parameters include a typical efficiency of 80%, a shutdown supply current of 80µA, and an operating temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Fixed 12V output voltage option within the LM2596 family
Integrated 3A power switch for high-current capability
Internal frequency compensation simplifies external component requirements
Thermal shutdown and current limit protection circuits

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for distributed power systems
Pre-regulators for switching regulators
Efficient buck converters for battery-powered applications

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'SX' confirms the TO-263 surface-mount package variant. Confirm the '-12' designation specifies the fixed 12V output version. Check datasheet revisions for any updates regarding lead-free compliance or pinout consistency with legacy National Semiconductor versions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 12V output is required without external feedback resistors. Ensure the input voltage remains within the 4.5V to 40V range. Verify thermal management capabilities for the TO-263 package if the full 3A load is utilized continuously.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2596 series of monolithic integrated step-down switching regulators. The 'SX' suffix denotes the D²PAK (TO-263) surface-mount package, distinguishing it from the through-hole TO-220 variant. It is a mature product originally developed by National Semiconductor before acquisition by Texas Instruments.
