LM2596SX-ADJ/J7002158

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596SX-ADJ/J7002158 is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments. It operates with an input voltage range of 4.5 V to 40 V and provides an adjustable output voltage from 1.2 V to 37 V. The device supports a maximum output current of 3 A with a fixed switching frequency of 150 kHz. It utilizes a TO-263-5 surface-mount package and functions within a junction temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the J7002158 suffix 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 component matches the standard LM2596SX-ADJ/NOPB electrical specifications and pinout configuration before integration into designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing buck converters requiring up to 3 A load current with minimal external parts. The 150 kHz switching frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the required output voltage falls within the 1.2 V to 37 V adjustable range and that the input voltage does not exceed 40 V.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2596 series, a family of monolithic integrated circuits designed for easy-to-use step-down switching regulators. The series includes fixed voltage options (3.3V, 5V, 12V) and an adjustable version. The SX suffix indicates the D2PAK (TO-263) surface-mount package, distinguishing it from the through-hole T-series variants.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2596SX-ADJ/NOPB is the direct equivalent part number with identical electrical characteristics and pinout. Other LM2596SX-ADJ variants from different manufacturers may require verification of pin compatibility and thermal performance.
