This EVK was developed for ROHM’s synchronous buck DC/DC converter BD9B304QWZ. The BD9B304QWZ accepts a power supply input range of 2.7V to 5.5V, and generates an output voltage from 0.8V to 0.8 x VIN using external resistors. It has a built-in 40mΩ N-channel MOSFET for High side and Low Side that is operating frequency is 1.0MHz/2.0MHz selectable.
