Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix PWR2G indicates tape and reel packaging when sourcing. Confirm the part status as discontinued or active through official onsemi channels before finalizing design-in decisions. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check for any updated revision notes that may affect pinout or electrical characteristics compared to earlier versions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Choose this component when both buck and boost capabilities are required in a single IC. The 3.4A current rating suits moderate power applications. Consider the 16-SOIC package for ease of assembly if surface mount is preferred. Evaluate the need for external components based on the desired switching frequency and output voltage settings. Verify thermal performance under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the NCV3163 family of switching regulators. It shares core functionality with variants like NCV3163PWG but differs in packaging and reel configuration.
