Bellnix Co., Ltd. (Headquartered in Saitama City, Saitama, Japan, President and CEO: Kenichiro Suzuki), a 47-year-old power supply manufacturer that designs, develops, and sells power supply products for industrial applications such as communication equipment, medical devices, and broadcasting equipment, will release Communication-feature-embedded POL Converter “BDA Series” on July 22, 2025.
The specifications on this product were determined through repeated discussion with FPGA manufacturers in order to be suitable for the devices fabricated using 10-nanometer or narrower processes. The main features are as follows.
-Features-
Communication Function
By using the communication function via PMBus, the output voltage can be adjusted to be optimal state based on the commands from FPGA, the state can be monitored, and the settings such as start-up sequence can be changed.
High Precision Output Settings
The high precision of +/-1% is achieved on output settings, This allows the output voltage to be supplied well within FPGA’s acceptable voltage range.
High Efficiency
Efficiency of 90% is realized.
High-speed Response
Very fast response is realized, suitable for the devices that required current rapidly and largely change, such as FPGAs.
Small Size, High Power Density
SMD package, with dimensions of 27.0 x 16.5 x 4.0 mm.
EVM and GUI
For evaluation environment, we can provide the evaluation board and communication adapter.
Using dedicated GUI provided free of charge, various settings can be changed on your PC display for easy evaluation.
