Procurement Notes

Verify the specific suffix E2 indicates RoHS compliance and environmental specifications as per the manufacturer's datasheet. Confirm the package type VQFNV3030-EP-16 matches your PCB footprint requirements. Ensure the operating temperature range of -20°C to +100°C aligns with your application's thermal environment. Cross-reference the pinout diagram with your schematic design to prevent integration errors.

Selection Notes

Select this component when an input voltage between 7.5 V and 15 V is available and a single output channel is sufficient. It is suitable for applications requiring up to 2 A output current with moderate switching frequencies. Consider this part if low standby current is critical for battery life or efficiency. Evaluate the thermal performance in the VQFNV3030-EP-16 package against your board's heat dissipation capabilities.
