Product Details
Key Features
Documentation

HFC0300 is a variable off-time controller that uses a fixed-peak–current technique to decrease its frequency as the load lightens. As a result, it offers excellent efficiency at light-load while optimizing the efficiency under other load conditions. When the frequency decreases to threshold, the peak current decreases with the decreasing load to prevent mechanical resonance in the transformer. The controller enters burst mode when the output power falls below a given level. The HFC0300 features various protections such as thermal shutdown, VCC under-voltage lockout, overload protection, short-circuit protection, and over-voltage protection. The HFC0300 is available in SOIC-7 package.

YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) 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 HFC0300HS-LF, and what package does it use?

HFC0300HS-LF is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Power Management 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 HFC0300HS-LF datasheet above.

Why is dynamic quotation used instead of a fixed price for HFC0300HS-LF?

Electronic component spot-market pricing for HFC0300HS-LF 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.

What is the delivery timeline after placing an order for HFC0300HS-LF?

Lead times for HFC0300HS-LF 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.
