Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2574HVMX-5.0/NOPB

LM2574HVMX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2574HVMX-5.0/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, designed for high-voltage input applications. It operates with an input voltage range of 4 V to 60 V and provides a fixed 5 V output at up to 500 mA. The device utilizes a buck topology with a typical switching frequency of 58 kHz. It is housed in a surface-mount SOIC-Wide-14 package and supports an operating temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic controller simplifies design by requiring minimal external components
Fixed internal switching frequency reduces component size and cost
Built-in thermal shutdown protects against overheating under fault conditions

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply systems requiring high input voltage tolerance
Battery-powered equipment needing efficient step-down conversion
On-card regulation modules for industrial control circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB confirms lead-free and RoHS compliance status as per manufacturer specifications. Confirm the SOIC-Wide-14 package variant matches your PCB footprint requirements. Ensure the 5.0V fixed output version aligns with your circuit design needs before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed standard low-voltage regulators' limits but remain below 60 V. The 500 mA current rating suits moderate load applications. Consider the 58 kHz frequency for balancing efficiency and passive component size compared to higher-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2574HV series, which extends the standard LM2574 family to handle higher input voltages up to 60 V. It shares the SIMPLE SWITCHER architecture with other members like the LM2574M-5.0/NOPB but differs in maximum input voltage capability and package type.
