Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer source, as National Semiconductor assets are managed by Texas Instruments. Confirm the specific suffix indicates the HV version and PDIP packaging. Ensure the part number matches the required fixed 5.0 V output specification and check for RoHS compliance status.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a simple, low-component-count buck converter with a fixed 5 V output. It is suitable where input voltages may reach up to 60 V and moderate efficiency at 150 kHz switching frequency is acceptable. Consider the through-hole PDIP package for prototyping or specific mechanical constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2594 series of SIMPLE SWITCHER power converters. The 'HV' designation indicates high-voltage input capability (up to 60 V), distinguishing it from standard versions. The 'N' suffix typically denotes the PDIP package type, while '-5.0' specifies the fixed output voltage.
