POWER MANAGEMENT EVALUATION KITS
These kits are valuable during the design and development phase of electronic devices because they allow engineers to:
-
Evaluate Performance: Test the performance of the PMIC under different conditions (voltage levels, loads, temperatures, etc.).
-
Verify Compatibility: Ensure the PMIC integrates well with other components and systems.
-
Optimize Power Efficiency: Fine-tune power management settings to achieve optimal efficiency for the device.
-
Prototype Development: Use the evaluation kit to prototype circuits and systems before committing to a final design.
Overall, power management evaluation kits accelerate the development process by providing a controlled environment for testing and refining power management solutions.

RASPBERRY PI POWER MANAGEMENT EVALUATION KITS
Digital Rep's engineers have designed a better solution for the shortcomings of Raspberry Pi power supplies.
The Raspberry Pi, while a very capable and useful single-board computer, is often used with less than ideal power supplies. The Raspberry Pi monitors the incoming power and can both warn the user and slow down the system (clock throttling) to reduce power consumption. It is very common to have issues with SD Card corruption that can be traced back to power input issues as well. The simple solution presented by many kit vendors is to supply a power supply that provides 5.1V rather than the 5.0V nominal, in hopes that the extra voltage compensates for resistive losses in the cabling and by providing additional headroom over the 4.63V undervoltage warning level. However, a large contingent of would-be makers simply use a cellular phone charger and hope for the best. On older models, the power draw was somewhat lower but as of the latest 3B and 4 models the recommended supply current has risen to 3A.[1] Additionally, most USB chargers perform poorly at higher loads and may even drop out, hiccupping power to the SBC.
With this in mind, we’ve designed a DC/DC converter using the Vishay SiC-468 that can use common higher voltage power supplies such as a laptop “brick”, converting a 10-28V supply voltage to a very dependable 5V/3A output. The efficiency is typically above 92%, which is not only good for the environment but also keeps heat buildup to a minimum.
All source code is available at our source repository to offer complete guidance and assist in setup and troubleshooting.
Our goal is to enable a designer to quickly evaluate the Vishay SiC-468 converter and extend its use to new use cases.
The product lines we bring to the market are at the forefront in their respective categories.
Our partners bring a unique and complementary array of product which enables us to work very effectively with our customers design needs across their entire architecture.
