LM2596SX-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596SX-ADJ is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150 kHz step-down voltage regulator. It provides an adjustable output voltage ranging from 1.2 V to 37 V with a maximum output current of 3 A. The device operates within an input voltage range of 4.5 V to 40 V and utilizes a Buck topology. Packaged in a TO-263-5 surface-mount format, it supports operation across a temperature range of -40 °C to +125 °C.

• Pre-regulator circuits for switching regulators

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SX' corresponds to the TO-263-5 surface mount package configuration required for your design. Confirm that the 'ADJ' designation indicates the adjustable output variant rather than a fixed voltage version. Ensure compliance with RoHS standards if applicable to your manufacturing process. Cross-reference the manufacturer part number against official TI documentation to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an adjustable output voltage up to 37 V is required with high current capability. Consider the 150 kHz switching frequency for balancing filter size and efficiency. Evaluate thermal management needs due to the 3 A output capacity. Compare against fixed-output variants if a specific voltage like 5 V or 12 V suffices for the application.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2596 series of SIMPLE SWITCHER converters, designed for efficient DC-DC buck conversion. It complements other variants such as LM2596S-5.0 and LM2596S-12 by offering flexible voltage adjustment. The series is known for requiring minimal external components, simplifying the design of step-down power supplies in industrial and commercial applications.
