Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and electrical characteristics. Ensure the ordering code matches the required output voltage and package type. Cross-reference manufacturer documentation to validate RoHS compliance status and environmental certifications before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15V output is required from a high-voltage source up to 60V. The through-hole PDIP package suits prototyping or applications where surface-mount processes are not feasible. Consider the 500mA output limit and 58kHz switching frequency when designing passive components for the target application.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2574HV series, which offers simplified design compared to traditional regulators by integrating the controller and power switch. The 'N' suffix indicates the PDIP package variant, while '15' specifies the fixed 15V output version. It serves as a cost-effective solution for medium-power DC-DC conversion tasks.
