MC34717EP

Overview

The NXP MC34717EP is a dual synchronous buck switching regulator featuring integrated N-channel power MOSFETs. It operates with a primary input voltage of 6.0 V and provides two independent outputs ranging from 0.7 V to 3.6 V. Each channel supports an output current of 5 A at a switching frequency of 1.0 MHz. The device is housed in a 26-pin QFN (5x5 mm) package, designed for space-efficient applications requiring high integration.

Feature Summary

• Dual synchronous buck architecture with integrated N-channel power MOSFETs
• Highly integrated design for space efficiency
• Supports wide output voltage adjustment range

Applications

• DDR voltage regulation
• Car audio amplifier boards
• Legacy electronic hardware repair

Procurement Notes

Verify the specific suffix (e.g., /R2) against the required reel quantity or tape-and-reel specifications. Confirm the package style matches the 26-QFN (5x5) footprint requirements. Ensure the manufacturer designation aligns with NXP Semiconductors or Freescale Semiconductor as applicable to the production batch.

Selection Notes

Select this component when a dual-output solution is required within a compact form factor. The 1.0 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 6.0 V input range and 5 A per channel current capability meet the system load requirements.

Part Context

This part belongs to the MC34717 family of special purpose regulators. It is classified under switching voltage regulators and is often associated with DDR voltage regulation tasks. The device represents a transition from older ZIP packages to modern surface-mount QFN technology for improved thermal performance and board space utilization.

Replacement Considerations

Check for MC34717EP/R2 variants which may differ in packaging format but share core electrical characteristics. Ensure any substitute maintains the 26-QFN pinout compatibility if board layout constraints are strict.
