Custom Services

Atlas Magnetics can create Custom PMICs or Custom Integrated Inductors for customers that incorporate the IP for integrated passives, advanced DC/DC architectures, and configurability

Application-Specific PMICs

Atlas Magnetics builds PMIC platforms using an advanced semiconductor process with industry-leading RDSon. PMIC output voltages range from 0.6V to 5.5V. Key features of Atlas Magnetics PMICs include:

1. Integrated Inductors for smallest footprints and thinnest solutions. These ICs contain fully integrated magnetics, not System-in-Packaging (SiP)

2. Advanced DC/DC architectures offering very high efficiencies and other benefits. Architectures include Multi-phase, high-frequency switching, Single Inductor Multiple Output (SIMO), and transformer-based DC/DC circuits.

3. Fast, Programmable, Low-Power Asynchronous control and mixed signal sensing for seamless interrupts, easy power sequencing , and unmatched low-power consumption.

4. Complete Software simulation and models of the available IP for easy system validation. (Available early 2023)

All PMICs are built around a cost structure equal to or better than discrete solutions. Atlas Magnetics was founded on the concept of using a single process and packaging type, coupled with identical testers and handlers, to drive high quality practices and best high-volume cost. See our Quality Commitment for details.

Integrated and Standalone Inductors

Contact Us above to discuss your product request.
Atlas Magnetics is making its integrated inductor technology available to the semiconductor IC design community. Until early 2023 all standalone and integrated inductor projects will be undertaken for completely custom, proprietary applications for individual end-customers. Atlas Magnetics is eager to discuss these collaborations with any groups that are a good fit for the values and considerations described below.

Unique Values of Atlas Custom Inductors

Thin: AM’s inductors are 0.18um to 0.36um of total thickness. The ideal inductor shape is a cube or sphere so discrete inductors with no height limitations will have a natural advantage vs. thin planar inductors when comparing inductance per unit area. However, planar inductors use flat wide copper coils with reduced skin effect so the impedance with increasing frequency is competitive and often superior to classic wire wound inductors.

IC packaging compatible: AM’s inductors are electroplated using in common semiconductor substrate material, Pb free, RoHs compatible, conflict free. This allows for complete power module products that are tested at the factory, less application support, and usually less EMI. All materials used in the AM’s inductors are common to the semiconductor industry

Cost effective: For the right volume AM’s inductors are competitive to discrete inductors from the highest volume vendors while providing new capabilities not possible with simple discrete inductors.

Easy to Multi Channel and Multi Phase: Since AM inductors are planar and built with electroplating processes multiple inductors can be designed for a single final package. Thus, multichannel ICs such as PMICs and SOCs which need multiple inductors are excellent candidates for Atlas Magnetics’ technology.

Ultra Flexible Geometry: Various inductor shapes and orientations can be realized to minimize crosstalk, field interference, or operation frequency. In addition, transformers, couple inductors, multi-tap coils can all be manufactured at market-leading sizes for little to no additional cost.

Considerations

Large Manufacturing Lots: Our manufacturing panel “wafer” containing the inductors on which an IC die can be mounted, over molded, and singulated into QFN style ICs contains up to 500,000 units per panel. This size allows Atlas Magnetics to offer very competitive pricing in high volume opportunities but not very competitive in low volumes. Each new project lot set up requires a roughly $20,000 USD charge to assemble and prepare the required machinery, which can be amortized across production lots, making it a small investment for large volumes but not necessarily feasible for small-volume projects. The specific lot charge will vary depending upon the complexity of the design.

Per Phase Current Limit: The magnetic devices are planar and so there is a point of diminishing performance improvement by continuing to increase the X and Y dimension of the inductor. For applications that require high current support or higher inductance it is recommended to use multiple inductors and switch to a multiphase type of architecture. There is no additional cost from an inductor(s) perspective while performance will be improved

Optimal Frequency Range: Our magnetic core inductors generally have a maximum frequency of between 2-4 MHz for good efficiency in DC/DC applications. Atlas Magnetics continues R&D work on increasing both the frequency response and current density of inductor offerings and expects to increase max frequency by 10x and current density by 3x before 2023.
