LM2595SX-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595SX-ADJ/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, featuring a fixed 150 kHz switching frequency. It operates as a step-down voltage regulator with an input voltage range of 4.5 V to 40 V and delivers up to 1 A output current. The adjustable output voltage spans from 1.2 V to 37 V. Housed in a TO-263-5 (D2PAK) surface-mount package, it supports a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic controller combining control circuitry, oscillator, and a 3-A rated internal switch for simplified design.
• Fixed high-frequency operation at 150 kHz allows for the use of small inductors and capacitors.
• Built-in thermal shutdown and current limit protection ensure robust operation under fault conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Efficient point-of-load DC/DC conversion
• Pre-regulator for linear post-regulators
• Standard 5-V bus stepping down to lower voltages

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SX' indicates tape-and-reel packaging when sourcing components. Confirm that the 'NOPB' designation ensures compliance with RoHS standards and absence of lead-based solder finishes. Cross-reference the manufacturer part number against official distributor catalogs to ensure authenticity and traceability before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a buck topology is required for converting higher input voltages to adjustable lower outputs. It is suitable for applications needing moderate current levels up to 1 A without external pass transistors. Consider the thermal performance of the TO-263 package for heat dissipation requirements in enclosed environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2595 series of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2596 but offers different current handling capabilities. The series is designed for straightforward implementation of non-isolated DC-DC converters with minimal external component count.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2595S-ADJ/NOPB serves as a direct pin-compatible alternative with tube packaging instead of reel. LM2596SX-ADJ/NOPB provides similar functionality but with a higher 3 A output current rating.
