SN61280D U2301 PMIC Rear Camera iPhone 7 7 Plus

Rear Camera PMIC for iPhone 7 and iPhone 7 Plus: Sensor Power Management

The SN61280D rear camera PMIC (board designation U2301) is the integrated circuit responsible for regulating and supplying power voltages to the photographic modules of the iPhone 7 and iPhone 7 Plus. This camera power management integrated circuit resolves severe electrical faults on the mainboard that prevent the image sensors from functioning.

Technical Specifications

• Part type: Camera PMIC Integrated Circuit
• Component reference: SN61280D (U2301)
• Compatibility: iPhone 7 (A1660, A1778, A1779); iPhone 7 Plus (A1661, A1784, A1785)

Technician Notes

• Test before applying: connect the part to the equipment and confirm its operation before securing or gluing it definitively. Thus, if there is any issue, the return or warranty is handled quickly and simply.
• Difficulty: Advanced (requires BGA micro-soldering and laboratory microscope).
• Access via disassembly of the mainboard, removal of the upper thermal shielding, and protection of neighboring components against excessive heat.
• Careful cleaning of the pads on the motherboard and application of a controlled thermal profile are recommended to avoid board warping.
• Measure the voltage output lines after soldering before reclosing the equipment completely.

What Distinguishes This Version

This OEM quality version meets the strict standards of assembly lines, ensuring the same voltage tolerance and thermal stability. It is the ideal selection for advanced repair technicians performing component-level interventions on the motherboard.

Frequently Asked Questions

Does this U2301 integrated circuit fit both models?
Yes, the SN61280D component is used in both the iPhone 7 and iPhone 7 Plus for camera power regulation.

Does replacing the SN61280D PMIC resolve focusing issues?
No, anomalies in the focusing motor or optical stabilization usually stem from the camera itself, whereas this component acts on the electrical power distribution.
