Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2596R-12

LM2596R-12

Voltage Regulators - DC DC Switching Regulators Overview

The HTC LM2596R-12 is a monolithic integrated circuit step-down switching regulator designed for efficient power conversion. It provides a fixed 12V output and supports up to 3.0A load current with excellent line and load regulation. The device operates from an input voltage range of 4.5V to 40V at a fixed 150kHz frequency. Packaged in TO-263-5 (D2PAK) surface-mount format, it integrates a 150kHz oscillator, thermal shutdown, and current limit protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Fixed 12V output version within the LM2596 series
Integrated 150kHz fixed-frequency internal oscillator
Built-in thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Simple high-efficiency step-down (buck) regulators
Efficient pre-regulators for linear regulators
On-card switching regulators
Power supply for battery chargers

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin, as TAEJIN Technology produces this component under license or as a secondary source compared to Texas Instruments. Confirm the specific suffix 'R' corresponds to the TO-263-5 package variant. Ensure compliance with RoHS directives if required by your application standards. Check moisture sensitivity level ratings for proper storage and handling procedures during assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 12V output is required from a higher input voltage rail. It is suitable for designs needing up to 3A continuous current without external pass transistors. Consider the TO-263-5 package for surface-mount applications requiring robust thermal performance. Verify that the 150kHz switching frequency aligns with your electromagnetic interference constraints and inductor selection.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM2596 series is a widely used family of buck converters known for simplicity and reliability. The 'R' suffix typically denotes the surface-mount D2PAK/TO-263 package variant, distinct from the through-hole TO-220 ('T') or smaller SOT-223 ('S') packages. This specific model offers a fixed 12V output, simplifying design by eliminating external feedback resistors needed for adjustable versions.
