MC34717EPR2

Overview

The MC34717EPR2 is a dual synchronous buck switching regulator from NXP Semiconductors, designed for space-efficient applications. It integrates N-channel power MOSFETs and operates with an input voltage range of 3 V to 6 V. The device provides two outputs with a maximum output current of 5.0 A per channel and utilizes a 1.0 MHz switching frequency. Packaged in a 26-QFN (5x5) case, it supports DDR voltage regulation. Key electrical parameters include an operating supply current of 35 mA and an operating temperature range of -40°C to 85°C.

Feature Summary

• Fully integrated dual synchronous buck architecture with embedded N-channel power MOSFETs
• Includes overcurrent protection, adjustable soft-start, and output discharge capabilities
• Optimized for DDR voltage conversion with high integration and low component count

Applications

• DDR voltage regulation
• Dual-output switching power supplies
• Space-constrained electronic systems requiring integrated power management

Procurement Notes

Verify the specific suffix EPR2 against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles defined in the product documentation. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when a compact solution for dual-output power generation is required. The integrated MOSFETs reduce external component count compared to discrete solutions. Verify that the 3 V to 6 V input range aligns with the system power rail. Consider the 26-QFN package constraints for thermal management and PCB layout requirements during the design phase.

Part Context

This part belongs to the MC34717 family of special purpose regulators. It is categorized under switching voltage regulators and PMICs. The series is characterized by high integration and efficiency, targeting mobile and consumer electronics where board space is limited. The EPR2 suffix typically denotes specific packaging or reel configurations within the standard MC34717 functional block.

Replacement Considerations

Check for direct pin-compatible alternatives within the MC34717 family, such as variants with different suffixes for packaging. Evaluate other dual synchronous buck regulators from NXP or competitors if specific thermal or current requirements differ. Ensure any substitute maintains the 1.0 MHz frequency and 5A capability.
