Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance as per manufacturer standards. Confirm the 10-MSOP package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any specific ordering quantity constraints associated with the reel packaging. Validate that the non-isolated topology aligns with your safety isolation requirements.

Selection Notes

Select this controller when both buck and boost functionalities are required in a single channel. Consider the 180kHz switching frequency for balancing efficiency and component size. Evaluate the 500mA output limit against your peak load demands. The wide input voltage range suits applications with fluctuating source voltages. Verify compatibility with external inductor and capacitor selections for stability.
