    EVB_ SY20493SUC_1

    The EVB_ SY20493SUC_1 is intended for evaluating a high efficiency, synchronous, step-up Boost converter SY20493. It can disconnect the output from the input during the shutdown mode. When input voltage exceeds the regulated output voltage, SY20493 enters bypass mode automatically.
