Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2574HVMX-3.3/NOPB

LM2574HVMX-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2574HVMX-3.3/NOPB is a SIMPLE SWITCHER step-down switching regulator manufactured by Texas Instruments, housed in a SOIC-Wide-14 surface-mount package. It delivers a fixed 3.3 V output at up to 500 mA with an input voltage range of 4 V to 60 V. Operating at a typical frequency of 58 kHz, the device supports buck and inverting topologies within an industrial temperature range of -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 stable regulation
Built-in thermal shutdown and current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply architectures
Pre-regulator stages for linear regulators
Battery-powered equipment requiring high efficiency

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance. Confirm the 'MX' designation indicates tape-and-reel packaging rather than tube. Ensure the specific voltage variant matches the required 3.3 V output specification before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed 40 V, as standard LM2574 variants are limited to 40 V. The wide input range accommodates higher bus voltages while maintaining a compact footprint. Verify that the 500 mA load requirement does not exceed the thermal dissipation capabilities of the chosen PCB layout.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2574HV series, designed for high-voltage applications compared to the standard LM2574 family. It provides a robust solution for converting higher DC voltages to lower regulated levels efficiently.
