Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized channels due to the NRND status. Confirm that the specific ordering suffix matches the required tape-and-reel packaging format. Ensure design reviews account for the end-of-life notification timeline to prevent supply chain disruptions during production phases.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for high-input voltage automotive applications requiring a compact solution. The wide input range accommodates cold-crash and load-dump conditions common in vehicle electrical systems. Evaluate thermal performance requirements based on the 500mA output current limit and the selected switching frequency.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM46000-Q1 series of SIMPLE SWITCHER converters. It shares architectural similarities with other automotive-grade buck regulators but is distinguished by its specific 60V input rating and 500mA output capacity. The PowerTSSOP package offers a balance between thermal dissipation and board space constraints.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate alternative Texas Instruments automotive buck converters with matching input voltage ranges and output current capabilities if redesign is necessary.
