- Evaluation Board - BD9B306NF-EVK-001
This Evaluation Board was developed for ROHM’s Single Synchronous Buck DC/DC Converter BD9B306NF-Z. BD9B306NF-Z is a synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. The output voltage can achieve a high accuracy due to ±1% reference voltage. It features fast transient response due to constant on-time control system. The Light Load 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. It achieves high power density and offers a small footprint on the PCB by employing 6pins in a 1.5mmx1.5mm small package.
