MC34712EP

Overview

The MC34712EP is a fully integrated DDR switch-mode power supply designed by NXP USA Inc. It functions as a single synchronous buck converter with integrated N-channel power MOSFETs, operating at a switching frequency of 1.0 MHz. The device supports an input voltage range of 3V to 6V and provides one output channel capable of delivering up to 3.0 A. Packaged in a 24-VFQFN exposed pad (4x4 mm) format, it offers a space-efficient solution for DDR memory voltage regulation applications.

Feature Summary

• Fully integrated DDR switch-mode power supply with synchronous buck topology
• Integrated N-channel power MOSFETs for high efficiency and compact design
• Operates at a fixed 1.0 MHz switching frequency to minimize external component size

Applications

• DDR memory voltage regulation
• Mobile device power management systems
• Embedded systems requiring compact DC-DC conversion

Procurement Notes

Verify the specific suffix 'EP' corresponds to the 24-QFN-EP package variant when sourcing. Confirm moisture sensitivity level (MSL) and lead-free soldering compatibility requirements against your assembly process specifications. Ensure the supplier provides valid traceability documentation for this NXP Semiconductors part number.

Selection Notes

Select this component when a highly integrated, low-profile solution is required for DDR memory power rails. The 1.0 MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Verify that the 3A current capability meets the peak load demands of the target memory subsystem within the 3V to 6V input range.

Part Context

This part belongs to the SMARTMOS 34712 family of power management ICs. It is categorized under Special Purpose Regulators within the Power Management (PMIC) segment. The EP suffix typically denotes the specific QFN package type with an exposed thermal pad for improved heat dissipation and mechanical stability.

Replacement Considerations

Consult official NXP documentation for direct pin-to-pin replacements or functional equivalents within the same product line. Cross-reference electrical parameters such as output current, switching frequency, and package dimensions before substituting with components from other manufacturers.
