LM2574HVM-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2574HVM-12 is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, designed for high-voltage input applications up to 60 V. It provides a fixed 12 V output with a maximum current of 500 mA. The device operates at a switching frequency of 58 kHz and supports both buck and inverting topologies. It is housed in a SOIC-Wide-14 package and functions within an operating temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix indicates the tube packaging variant rather than tape-and-reel. Confirm RoHS compliance status through official documentation. Ensure the manufacturer source is Texas Instruments or authorized distributors to avoid counterfeit components. Check for moisture sensitivity level requirements during storage and handling.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed 40 V but remain below 60 V. Choose the HV variant over standard versions for higher voltage tolerance. Consider the SOIC-Wide-14 package for thermal performance needs. Verify that the fixed 12 V output meets system requirements without external adjustment.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2574HV series, which extends the standard LM2574 capabilities to handle higher input voltages. This family offers a balance of ease of use and flexibility for designers requiring robust step-down regulation in demanding environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2574HVMX-12/NOPB serves as the reel-packaged equivalent. LM5574 offers similar functionality with a 75 V input rating.
