If the input voltage (VIN) is larger than the output voltage (VOUT) by a diode drop (VDIODE varies from ~0.2V at light load to ~0.7V at heavy load), then the output voltage is clamped to a diode drop below…
When EN is falling, the minimum voltage threshold is 300mV. When EN is rising, the maximum voltage threshold is 850mV. Make sure the voltage on EN pin falls below 300mV to disable the output, and the voltage…
