    EVB_SY20489ADC_1

    The EVB_SY20489ADC_1 is intended for evaluating a high efficiency, synchronous, step-up boost converter SY20489. It can disconnect the output from input during the shutdown mode. When input voltage exceeds the regulated output voltage, SY20489 enters bypass mode automatically.
