MC34716EPR2

Overview

The MC34716EPR2 is a dual synchronous buck switching regulator designed for DDR power applications. 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. It features a fixed switching frequency of 1.0 MHz and is housed in a 26-terminal HVQFN package measuring 5 mm x 5 mm. The component supports surface mount mounting and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Highly integrated dual synchronous buck architecture with embedded power MOSFETs
• Space-efficient design suitable for dense PCB layouts
• Fixed high-frequency operation for reduced external component size

Applications

• DDR memory power supply systems
• Dual-output DC-DC conversion for portable electronics
• Low-voltage high-current regulation in mobile devices

Procurement Notes

Verify the exact suffix EPR2 against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the intended thermal management solution, as the exposed pad requires proper soldering for heat dissipation. Cross-reference the ordering part number with authorized distributors to avoid counterfeit components and confirm availability status.

Selection Notes

Select this component when a compact dual-output solution is required for low-voltage digital loads. The 1 MHz switching frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load current requirements do not exceed the 5A per channel limit and that the input voltage remains within the 3V to 6V operational window for stable regulation.

Part Context

This part belongs to the MC34716 family of special purpose regulators from NXP Semiconductors. It is specifically engineered for power management in mobile and handheld devices where space and efficiency are critical constraints. The EP variant denotes the specific package configuration used in this product line.

Replacement Considerations

Check for direct pin-compatible substitutes within the same NXP family or equivalent dual-buck controllers from other manufacturers. Ensure replacement parts match the 26-QFN footprint and thermal characteristics. Verify that alternative components support the same 3V-6V input range and 5A output capability.
