MC34712EPR2

Overview

The MC34712EPR2 is a highly integrated, space-efficient single synchronous buck switching regulator manufactured by NXP Semiconductors. It functions as a 3.0 A DDR switch-mode power supply with a maximum switching frequency of 1000 kHz. The device utilizes voltage-mode control and is housed in a 24-VFQFN exposed pad package measuring 4 mm x 4 mm. It operates within an ambient temperature range of -40°C to 85°C and is designed for surface mount applications.

Feature Summary

• Fully integrated single synchronous buck architecture
• High switching frequency operation up to 1 MHz
• Space-efficient HVQFN24 package design

Applications

• DDR memory power supply regulation
• General purpose DC-DC conversion
• Embedded system power management

Procurement Notes

Verify the specific ordering suffix 'R2' against the manufacturer's current product status documentation. Confirm that the component is available in tape and reel packaging as indicated by the suffix. Ensure the procurement channel provides valid traceability for the NXP Semiconductors brand. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when a compact, high-frequency synchronous buck solution is required for DDR applications. The 3A output capability suits moderate load requirements. Consider the 24-QFN package for board space constraints. Evaluate thermal performance based on the exposed pad design. Verify input voltage ranges against the specific application requirements before finalizing the selection.

Part Context

This part belongs to the MC34712 series of switching regulators from NXP Semiconductors. It is derived from Freescale Semiconductor technology, which was acquired by NXP. The component represents a specialized power management IC designed for digital applications requiring efficient voltage conversion in small form factors.

Replacement Considerations

Check NXP official discontinuation notices for potential obsolescence. Identify direct pin-compatible alternatives within the same family if available. Verify electrical parameters match exactly for any substitute components.
