LM2594HVMX-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVMX-12/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments. It operates with an input voltage range of 4.5 V to 60 V and provides a fixed 12 V output at up to 500 mA. The device utilizes a buck topology with a switching frequency of 150 kHz. It is housed in an 8-SOIC surface-mount package and supports an operating temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch for simplified design
• Fixed internal feedback network for standard output voltages
• Built-in thermal shutdown and current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Pre-regulator stages for downstream linear regulators
• Battery-powered equipment requiring efficient step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number includes the /NOPB suffix, as this indicates lead-free compliance and RoHS adherence. Confirm the 'HVM' designation matches the required 60V input capability rather than the standard 40V variant. Ensure the 'MX' suffix corresponds to the SOIC-8 tape-and-reel packaging format required for automated assembly processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from a high-voltage source up to 60V. The 500mA current limit suits low-to-medium power applications. Consider the 150kHz frequency for balancing component size against efficiency. Verify that the SOIC-8 package thermal performance meets the specific PCB layout requirements for the expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2594HV series, designed for high-input voltage applications. It differs from the standard LM2594 by supporting inputs up to 60V. The 'MX' suffix denotes the surface-mount SOIC-8 package, while '/NOPB' confirms environmental compliance. It serves as a robust solution for industrial and automotive power management where space and efficiency are critical.
