LM2595S-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595S-ADJ/NOPB is a SIMPLE SWITCHER® power converter featuring an integrated 1-A switch. It operates as a step-down voltage regulator with a switching frequency of 150 kHz. The device supports an input voltage range from 4.5 V to 40 V and provides an adjustable output voltage between 1.2 V and 37 V. It utilizes a TO-263-5 surface-mount package. Key electrical parameters include a maximum output current of 1 A, a typical quiescent current of 85 µA in shutdown mode, and operation across a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and functional equivalence. Confirm RoHS compliance status via the manufacturer's datasheet. Ensure the TO-263-5 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, high-efficiency buck topology is required with an input voltage up to 40 V. It is suitable for designs needing an adjustable output voltage within the 1.2 V to 37 V range. Consider the 150-kHz switching frequency for balancing component size and efficiency. Verify that the 1-A output current meets the load requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2595 series of SIMPLE SWITCHER® power converters from Texas Instruments. It is designed as a drop-in replacement for older discrete solutions or less efficient linear regulators. The series includes fixed-output variants alongside this adjustable version, sharing common internal architecture and protection features.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct equivalents such as the LM2595SX-ADJ/NOPB variant which shares the same core functionality but differs in packaging format. Verify if legacy non-NOPB versions are available as temporary substitutes, noting potential differences in environmental compliance.
