    EVB_SY20492AABC_1

    The EVB_SY20492AABC_1 is intended for evaluating a a high efficiency, synchronous, step-up Boost converter SY20492A. It can disconnect the output from the input during the shutdown mode. When input voltage exceeds the regulated output voltage, SY20492A enters bypass mode automatically.
