LM2595S-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The UMW LM2595S-ADJ is a switching voltage regulator belonging to the SIMPLE SWITCHER power converter series. It operates as a step-down (buck) DC-DC converter with a fixed internal oscillator frequency of 150 kHz. The device supports an input voltage range from 4.5 V to 40 V and provides an adjustable output voltage ranging from 1.2 V to 37 V. It delivers a maximum output current of 1 A through a single output channel. The component 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 Feature Summary

• Integrates a 150 kHz fixed-frequency internal oscillator to enable the use of smaller external filter components compared to lower-frequency regulators.
• Features TTL-compatible shutdown capability, allowing logic-level control for entering low-power standby modes.
• Incorporates built-in thermal shutdown and current limiting protection mechanisms to enhance operational reliability.

Voltage Regulators - DC DC Switching Regulators Applications

• Efficient step-down (Buck) voltage regulation
• Pre-regulator for linear voltage regulators
• On-board switching voltage conversion
• Positive-to-negative voltage conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number matches the manufacturer's official documentation for the LM2595S-ADJ variant. Confirm the package type is TO-263-5 and ensure compatibility with the required input and output voltage ranges. Check for RoHS compliance status and moisture sensitivity levels before integration into the design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 1 A buck converter is required with an input voltage up to 40 V. The adjustable output feature allows flexibility in setting the desired voltage level using external resistors. Ensure the application benefits from the 150 kHz switching frequency for reduced passive component size while maintaining standard efficiency levels.

Voltage Regulators - DC DC Switching Regulators Part Context

This component is part of the LM2595 family of SIMPLE SWITCHER power converters manufactured by Texas Instruments. The LM2595 series includes both fixed-output and adjustable versions, designed to simplify the design of switching regulators. The 'S' suffix indicates the surface-mount TO-263 package, while 'ADJ' denotes the adjustable output configuration.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include the LM2595S-ADJ/NOPB from Texas Instruments. Other variants within the LM2595 series may be considered if fixed output voltages are acceptable instead of adjustable ones.
