Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2594HVMX-3.3/NOPB

LM2594HVMX-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVMX-3.3/NOPB is a Texas Instruments SIMPLE SWITCHER power converter featuring a fixed 3.3V output and 0.5A current capability. It operates from a 4.5V to 60V input range using a buck topology at a 150kHz switching frequency. The device integrates a 150mA driver, thermal shutdown, and current limit protection. Packaged in an 8-pin SOIC surface-mount case, it supports operation between -40°C and +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-voltage switch rated for up to 60V input
Fixed internal feedback network for simplified design
Built-in thermal shutdown and current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for industrial systems
Pre-regulation for downstream switching regulators
Battery-powered equipment requiring wide input ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free status and RoHS compliance. Ensure the 'MX' designation matches the required tape-and-reel packaging format rather than tube. Confirm the manufacturer is Texas Instruments or authorized National Semiconductor sources to guarantee authenticity and correct revision levels.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V rail is needed with inputs up to 60V. It suits designs prioritizing simplicity over adjustable precision. Consider alternative models if higher efficiency or lower quiescent current is critical, as this series focuses on robust integration rather than ultra-low power consumption.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2594HV family of step-down converters. It shares the core architecture with adjustable variants but utilizes a fixed resistor divider for the 3.3V output. The HV designation indicates enhanced input voltage tolerance compared to standard LM2594 devices.
