- Evaluation Board - BD9DA00MF-EVK-001
This Evaluation Board was developed for ROHM’s Single Synchronous Buck DC/DC Converter BD9DA00MF. BD9DA00MF is a synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. It can provide current up to 12 A. It features fast transient response due to constant on-time control system. The Light Load Mode (LLM mode) control improves efficiency in light-load conditions. It is ideal for reducing standby power consumption of equipment. Power Good function makes it possible for system to control sequence.
