LM2594HVMX-ADJ/NAK1

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVMX-ADJ/NAK1 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a high-voltage step-down voltage regulator. It operates with an input voltage range of 4.5V to 60V and provides a positive adjustable output voltage starting from 1.2V. The device delivers a maximum output current of 500mA through a single output channel. It utilizes a buck topology with a fixed switching frequency of 150kHz. The component is housed in an 8-pin SOIC package and supports surface-mount installation. It is rated for operation within a junction temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix NAK1 against official Texas Instruments documentation, as this designation may indicate obsolete status or specific manufacturing lot characteristics. Confirm availability through authorized distributors, as standard NOPB variants are more commonly stocked. Ensure the procurement source provides valid traceability for this discontinued or limited-production part number.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high-input voltage buck converter with integrated synchronous rectification is required. The 150kHz frequency balances size and efficiency. Compare against the LM2594HVMX-ADJ/NOPB if standard packaging is preferred. Ensure the application demands the specific thermal and electrical characteristics of the NAK1 variant before finalizing the bill of materials.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2594HV series of SIMPLE SWITCHER converters. These devices are designed for small-power, wide-input-voltage-supply applications. The series typically includes fixed and adjustable output versions. The HVMX suffix indicates a tape-and-reel SOIC package variant, distinguishing it from tube-packaged DIP or standard SOIC parts.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2594HVMX-ADJ/NOPB is a direct functional substitute within the same family. Verify pin compatibility and thermal performance when swapping between the NAK1 and NOPB suffixes.
