• Features built-in thermal shutdown and cycle-by-cycle current limiting for protection

Voltage Regulators - DC DC Switching Regulators Applications

• Automotive electronics systems requiring AEC-Q100 qualification
• Industrial distributed power architectures
• On-board DC/DC conversion modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status directly on the manufacturer's official datasheet or ordering information page. Confirm the package designation matches the required TO-263-7 footprint for PCB layout compatibility. Ensure the 'ADJ' variant aligns with the target adjustable voltage requirements rather than fixed-output alternatives.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust 3A buck converter is needed for wide input voltage ranges up to 42V. The TO-263-7 package provides superior thermal dissipation compared to smaller surface-mount options. Consider the 500kHz switching frequency for balancing component size and efficiency. Verify that the application environment meets the specified -40°C to +125°C operating temperature limits.
