Hi,
As per datasheet, CIN greater than CL is recommended. To avoid current flow through the body diode from VOUT to VIN when the system supply is removed.
In my design QOD shorted to VOUT for fast output discharge during Power OFF. Still the above statement is valid ? Since the output voltage will get discharged through the QOD pin instead of body diode?
More Info : 10uF connected to VIN pin and 1uF connected to VOUT pin of TPS22918-Q1 in my design. The VOUT goes to one PHY device IO Supply pin and PHY device vendor recommended to connect 47uF bulk cap. So 47uF connected to load side. Is this cause any issue ?
