LM2594M-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594M-ADJ is a step-down switching regulator IC manufactured by UMW, belonging to the SIMPLE SWITCHER family. It operates with an input voltage range of 4.5V to 40V and provides a single adjustable output from 1.23V to 37V. The device delivers up to 1.5A of output current at a fixed switching frequency of 150kHz. Packaged in an 8-SOP surface-mount format, it supports junction temperatures between -40°C and 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic buck converter topology for efficient DC-DC step-down conversion
• Adjustable output voltage capability via external resistor network
• Built-in thermal shutdown and current limiting protection mechanisms

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Pre-regulator stages for linear post-regulators
• Battery-powered equipment power management

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify manufacturer origin as UMW rather than Texas Instruments. Confirm package marking matches 8-SOP specifications. Check RoHS3 compliance status against specific batch documentation. Ensure ordering suffix corresponds to tape-and-reel or cut-tape requirements. Validate datasheet revision matches component date code.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when higher continuous current capacity than standard 500mA variants is required. Suitable for designs needing wide input voltage ranges up to 40V. Consider thermal performance in enclosed environments due to SOIC package constraints. Verify external component selection aligns with 150kHz switching frequency requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2594 series of non-synchronous buck converters. Differs from LM2594HV which supports higher input voltages. Distinct from LMX2594 which is an RF synthesizer. Shares functional similarities with LM2596 but offers different current ratings and pin configurations.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2594MX-ADJ/NOPB (Texas Instruments) offers similar functionality with 500mA rating. LM2594M-12/NOPB provides fixed 12V output instead of adjustable. Cross-reference pinouts and thermal characteristics before substitution.
