LM2596T-12/SL110273

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596T-12 is a monolithic integrated circuit step-down (buck) switching regulator from the Texas Instruments SIMPLE SWITCHER family. It provides all active functions for a buck converter capable of driving a 3A load with excellent line and load regulation. The device operates with an input voltage range of 4.5V to 40V and delivers a fixed 12V output. It utilizes a 150kHz internal oscillator, allowing for the use of small inductors and capacitors. The component is housed in a TO-220 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated power switch rated for 3A continuous load current
• Fixed 12V output option within the SIMPLE SWITCHER series
• Internal frequency compensation simplifies external component selection
• Built-in thermal shutdown protects against overheating

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load DC/DC conversion modules
• Pre-regulators for linear post-regulators
• Efficient battery-powered systems requiring step-down topology

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix SL110273 against official Texas Instruments documentation to confirm it denotes a standard commercial grade variant or a specific tape-and-reel configuration. Ensure the ordering part number matches the required TO-220 through-hole package and RoHS compliance status before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required at up to 3A with minimal external parts. It is suitable for designs prioritizing high efficiency over ultra-low quiescent current. Consider the TO-220 package for adequate heat dissipation without additional heatsinking under moderate loads.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2596 series of SIMPLE SWITCHER power converters. The 'T' indicates a TO-220 package, while the '-12' specifies the fixed 12V output version. The series is designed for high-efficiency step-down applications using a 150kHz switching frequency.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible replacements include the LM2596T-12/NOPB. Verify that any substitute maintains the same 3A current rating, 40V maximum input voltage, and TO-220 footprint.
