ADuM4470 / ADuM4471 / ADuM4472 / ADuM4473 / ADuM4474 is a four-channel digital isolator with integrated regulated DC-DC isolated power supply controller and integrated internal MOSFET driver. The DC/DC controller has a built-in isolated PWM feedback on the primary side, using iCoupler®chip-level transformer technology and complete loop compensation. It is not necessary to use an optocoupler for feedback and to compensate the loop for stability.Compared to unregulated isolated DC/DC power supplies, ADuM447x isolators can provide a more stable output voltage and higher efficiency. It is packaged in a wide-body SOIC, fully integrated feedback and loop compensation, providing a smaller size and 8.3 mm creepage distance solution. Regulated feedback can provide a relatively flat efficiency curve over the entire output power range. AduM3070 can enable a DC/DC converter with an isolated output voltage range of 3.3 V to 24 V from an input voltage of 5.0 V or 3.3 V, with an output power of 2.5 WADuM447x isolators provide four independent isolation channels, supporting multiple channel configurations and data rates. (The ADuM447x mentioned in this data sheet represents ADuM4470 / ADuM4471 / ADuM4472 / ADuM4473 / ADuM4474)

YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.

  • 1. Certification Scope: Quality certifications apply only to the entities, sites and activities listed in valid certificates. Management system certification does not certify each individual product.
  • 2. Product Authenticity: Products must match the agreed manufacturer, part number and condition. Supplier screening and authenticity checks help reduce counterfeit risk.
  • 3. Inspection & Testing: The inspection scope follows product risks and agreed requirements. Additional testing, laboratory arrangements, costs and lead times require written confirmation.
  • 4. Traceability & Documentation: Request conformity certificates, traceability records or test reports before ordering. Document availability, issuer and coverage must be confirmed for the offered goods.
  • 5. Environmental Compliance: RoHS and REACH information is based on applicable manufacturer documentation. Confirm the exact part, declaration date and relevant exemptions before ordering.
  • 6. Handling & Protection: Handling, storage and packaging follow applicable product requirements, including ESD and moisture protection where required. Special handling requirements must be agreed before ordering.

Product FAQ
Purchasing FAQ

What type of component is ADuM4473, and what package does it use?

ADuM4473 is an authentic electronic component manufactured by Analog Devices, categorized under Integrated Circuits - ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official ADuM4473 datasheet above.

Why is pricing for ADuM4473 available via RFQ rather than a fixed checkout price?

Electronic component spot-market pricing for ADuM4473 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.

How quickly can ADuM4473 be shipped once quoted?

Lead times for ADuM4473 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
