    EVB_SY20489BADC_1

    The EVB_SY20489BADC_1 is intended for evaluating a high efficiency, synchronous, step-up boost converter SY20489B. It can disconnect the output from input during the shutdown mode. When input voltage exceeds the regulated output voltage, SY20489B enters bypass mode automatically.
