MC34716EP

Overview

The MC34716EP is a dual synchronous buck switching regulator IC designed for DDR voltage regulation. It integrates N-channel power MOSFETs and operates with an input voltage range of 3V to 6V. The device provides two independent outputs, each capable of delivering up to 5A. Output voltages are adjustable from 700mV to 3.6V. The unit functions at a fixed switching frequency of 1MHz and is housed in a 26-QFN (5x5) package.

Feature Summary

• Dual synchronous buck architecture with integrated N-channel power MOSFETs
• Designed specifically for DDR voltage regulation applications
• Space-efficient packaging suitable for dense board layouts

Applications

• DDR memory power supply systems
• Mobile device power management
• Embedded system voltage conversion

Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm the specific suffix EP matches the required package and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 26-QFN (5x5) form factor. Check for alternative sources if original manufacturing lines are discontinued.

Selection Notes

Select this component when dual low-voltage high-current rails are required for DDR interfaces. The 1MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 3V-6V input range aligns with the system's primary power source. Ensure thermal management strategies accommodate the 5A per channel capability within the QFN enclosure.
