Champs Technologies – high-efficiency, low-profile planar transformers and inductors

Since 1992, Champs Technologies has been designing and manufacturing planar transformers and inductors. They offer a specialist range of high efficiency, low profile products to enable customers to meet the needs of higher power and smaller applications, with quality assured by their up to date certifications such as ISO9001-2015, UL File #251699 and Conflict Minerals Compliant.

Champs Technologies are committed to providing high-quality and engineering-focused innovations, working in partnership with market-leading semiconductor manufacturers such as Linear Technology (today Analog Device), Texas instruments and On-semi to develop products fitting into their reference designs to help support customer projects.

What do we mean by the term “planar technology”?

A planar transformer or inductor are low-profile magnetic components which sits at the same level as the “motherboard” pcb. Planar cores reduce the space requirements, increase the power density and the overall performance. Its design and use is possible due to tooled ferrite core shapes that are available.

Champs Technologies provides a range of components based on ferrites ER, EE, PQ and other available, whose input voltage range is from few volts up to 400

Benefits of planar technology

  • Height: low profile
  • Low leakage inductance
  • Repeatable leakage inductance, capacitance
  • Volumetric efficiency (small size)
  • Low turns count improves Cu loss
  • Optimized core cross section lowers core loss
  • Large core surface promotes heat transfer
  • PCB construction yields lowest Cu loss
  • AC resistance and proximity Cu loss minimized
  • Opportunity to embed planar into PCB module

Cores for planar technology

High efficiency, low profile transformers and inductors

Champs Technologies' standard components are ideal for designers who need high efficiency, low profile planar transformers and inductors, which are ideal for high-frequency applications with restrictive space requirements. Their standard planar cores enable customers to adjust the leg length and window height without new tooling. The final core specification can be tailored to exactly accommodate the planar conductor stack height, with no wasted space.
