BD9F800MUX-EVK-001 uses BD9F800MUX to output 1V from a 12V input voltage. The input voltage of the BD9F800MUX is from 4.5V to 28V and the output voltage is configurable from 0.765V to 13.5V with external resistors. The switching frequency can be selected as 300 kHz or 600 kHz. BD9F800MUX is a constant on-time controlled DC/DC converter with fast transient response and does not require external phase compensation .
