Reference Design / Application Evaluation Kit
-
- Evaluation Board - BD9G500EFJ-EVK-001
This EVK is using not BD9G500UEFJ-LA, but BD9G500EFJ-LA. BD9G500EFJ-EVK-001 uses BD9G500EFJ-LA to output 5V from a 48V input voltage. The input voltage of the BD9G500EFJ-LA is from 7V to 76V and the output voltage is configurable from 1V to 0.97 x VIN V with external resistors. The operating frequency is configurable between 100 kHz and 650 kHz with an external resistor connected to RT pin. This is a current mode control DC/DC converter that provides fast transient response performance and simple phase compensation setup.
