LM2596S-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596S-ADJ is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150 kHz step-down voltage regulator. It operates with an input voltage range of 4.5 V to 40 V and provides an adjustable output voltage between 1.2 V and 37 V. The device supports a maximum output current of 3 A and utilizes a buck topology. Housed in a TO-263-5 surface-mount package, it is designed for efficient DC-DC conversion within an operating temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free and RoHS compliance when sourcing. Confirm the specific package variant matches the required PCB footprint. Ensure the supplier source aligns with Texas Instruments authorized distribution channels to guarantee component authenticity and traceability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model for applications requiring an adjustable output voltage up to 37 V with a 3 A load capacity. The TO-263 package offers a balance of thermal performance and surface-mount convenience. Consider the 150 kHz switching frequency when sizing external inductors and capacitors for optimal efficiency and ripple reduction.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2596 series of SIMPLE SWITCHER converters. It shares core architecture with fixed-output variants like the LM2596S-5.0 but allows user-defined output levels via external feedback resistors. The 'S' designation specifically identifies the TO-263 surface-mount package form factor.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2596S-ADJ/NOPB serves as the direct lead-free replacement for the non-compliant LM2596S-ADJ variant. Cross-referencing with other SIMPLE SWITCHER family members requires verification of pin compatibility and thermal characteristics.
