Coupled Inductor Buck – High‑Efficiency Power Conversion for US Industries

Reduce ripple, boost efficiency, and cut BOM cost with a single‑stage buck solution designed for OEM/ODM partners.

Why Traditional Buck Converters Miss the Mark

As a Purchasing Manager you’ve likely faced one or more of these issues:

• High price tags – generic parts from overseas often carry hidden freight and duty costs.
• Low efficiency – 80‑85% conversion leads to excess heat and larger heat‑sink budgets.
• Size constraints – Standard inductors increase PCB footprint, limiting product miniaturization.
• Inconsistent quality – Variable magnetic properties cause voltage ripple spikes.
• Long lead times – 8‑12 weeks from most suppliers stalls production schedules.

According to a 2025 industry survey, 63% of US manufacturers cite “inefficient power modules” as a top barrier to scaling new product lines.

Xinchangda’s Coupled Inductor Buck – The Competitive Edge

Our coupled inductor buck modules combine two magnetically‑linked inductors in a single package, delivering up to 95% efficiency while reducing ripple to ≤2 mVpk. Engineered in‑house, they meet ISO‑9001, CE, FCC, RoHS, and VDE standards.

• Powerful Factory – 14,000 m² facility, 14 automated lines, 450 k units/month capacity.
• Quality Assurance – 100% incoming material inspection, 6‑sigma process control.
• OEM/ODM Design – Custom winding, footprint, and packaging to match your PCB.
• High‑Speed Delivery – 5‑day express from Shenzhen port to US West Coast.
• Cost Transparency – FOB pricing, EX‑WORKS options, and volume‑based discounts.
