    EVB_SY20631QNC

    The EVB_SY20631QNC is intended for evaluating a high efficiency, synchronous, step-up Boost converter SY20631. It can disconnect the output fromthe input during the shutdown mode. When input voltage exceeds the regulated output voltage, SY20631 enters bypass mode automatically.
