Solving installation space and interference issues with semi-custom solutions! A case study of an electronics manufacturer that achieved significant miniaturization with the GaN series proposal
Limited installation space and interference with surrounding components are major factors that make power supply selection difficult. In this case, by proposing the GaN series, which achieved semi-custom support and significant miniaturization, we resolved issues that were difficult to address with standard products and realized a power supply configuration suitable for installation in the actual equipment.
"Size does not fit" "Interference occurs" Are you having trouble selecting a power supply?
As equipment becomes smaller and more densely integrated, power supply selection increasingly requires consideration not only of ratings but also enclosure size and shape, cable routing, display specifications, and safety standards.
In particular, issues such as not fitting in the installation space, interference when using an AC tap, and increased costs due to excessive specifications are often difficult to resolve through simple selection of standard products.
In this case, in response to these constraints, we proposed an optimal power supply through a semi-custom approach that reviews only the necessary specifications based on existing Products.
Challenges Before Implementation
When selecting a power supply for the customer's equipment, the following issues were identified.
| Issue | Details |
|---|---|
| Size | The existing AC/DC Power Adapter is too large and does not fit in the installation space |
| Interference | When using an AC power strip, it interferes with adjacent ports |
| Cost | The output specifications are overly generous, making cost optimization difficult |
| Specification adjustments | Adjustments tailored to actual usage are required, including cables and labeling |
It was difficult to achieve a balance between size, shape, specifications, and cost.
Our Solutions
In this project, rather than simply proposing a substitute product, we provided a semi-custom solution based on our existing lineup. After reviewing the usage environment and installation conditions, we selected the optimal series/model from multiple lineups and adjusted specifications where necessary for the base Products.
In particular, the proposal of the GaN series, which achieved up to 40% size reduction compared to conventional products, had a significant effect in resolving installation constraints. As a result, we optimized the specifications for actual use without the time and cost required for a full custom design.
Specific Optimization Points
| Optimization Item | Details |
|---|---|
| Selection of Base Products | Based on installation conditions and required specifications, the most suitable series and model were selected from multiple lineups |
| Utilization of the GaN Series | Proposed the GaN series, which is up to 40% smaller than conventional products, contributing to improved installation flexibility |
| Review of Output Specifications | Optimized specifications to match actual usage conditions while reducing excessive margins |
| Modification of Label Specifications | Adjusted labeling content to meet the customer's management and display requirements |
| Optimization of Cable Specifications | Reviewed cable conditions with consideration for installation and handling |
| Organization of Safety Standards | Organized required standards and evaluation conditions according to the intended application |
While using existing Products as a base, we cleared constraints that could not be addressed by standard products by organizing output specifications, labeling, cable conditions, and regulatory aspects according to the usage environment.
Effects After Implementation
| Effect | Details |
|---|---|
| Miniaturization | By proposing the GaN series, achieved up to 40% size reduction compared to conventional products |
| Installability | Achieved a size suitable for the installation space, eliminating the risk of AC tap interference |
| Cost | Optimized costs by refining specifications to what was necessary and sufficient |
| Adoption Decision | With specifications based on actual device installation, smooth adoption decisions became possible |
Achieved a realistically adoptable power supply configuration without design changes.
Customer Testimonials
 | "We were concerned about size and interference issues and felt that standard products would be difficult to use, but by reviewing the specifications based on existing products, we were able to adopt a solution without difficulty. In particular, the proposal to downsize using the GaN series had a significant impact and expanded our design flexibility within the limited space available. We were especially impressed that everything, including output requirements, cables, and label displays, was organized for us, allowing us to consider it not just as a product proposal but as a power supply tailored to our own equipment." - Development Representative, PC and Peripheral Equipment Manufacturer |
Do You Have Any of These Concerns?
| Standard products do not fit the required size or shape |
| It is difficult to achieve both miniaturization and performance |
| You want to slightly adjust the output specifications |
| You want to optimize cables and display content as well |
| Full custom solutions have high hurdles in terms of cost and delivery time |
We solve that challenge.
With our existing lineup and semi-custom support, we can achieve power supply specifications suited to actual use while keeping initial costs low and ensuring short lead times. We can also propose compact, high-efficiency Products, including our GaN series, so please feel free to consult with us even if "standard products are slightly unsuitable" for your needs.
