LM2594HVMX-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVMX-3.3/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150 kHz step-down voltage regulator. It provides a fixed positive output of 3.3V with a maximum output current of 500mA. The device accepts an input voltage range from 4.5V to 60V and operates within a temperature range of -40°C to +125°C. Housed in an 8-pin SOIC (D) package, it utilizes a buck topology for efficient DC-DC conversion.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number includes the NOPB suffix to confirm lead-free status and compliance with RoHS directives. Ensure the ordering code matches the specific tape-and-reel packaging format required for surface-mount assembly processes. Cross-reference the manufacturer's latest datasheet to confirm pinout compatibility and recommended operating conditions before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from a high-voltage source up to 60V. It is suitable for applications needing moderate current capability at 500mA with minimal external components. Consider the SOIC-8 package constraints for thermal management and PCB space. Verify that the 150kHz switching frequency aligns with electromagnetic interference requirements and inductor size constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2594HV series of SIMPLE SWITCHER converters. It shares architectural similarities with other members like the LM2594HVN-12 but differs in output voltage configuration and package type. The series is designed for high-efficiency step-down conversion, offering a robust solution for industrial and commercial power supply designs requiring wide input voltage ranges.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2594HVM-3.3/NOPB and LM2594HVMX-3.3 without the NOPB suffix if lead-free compliance is not critical. Other family members like LM2594HVM-5.0/NOPB offer different fixed voltages but share identical pinouts and electrical characteristics.
