TPS22913: Reverse current protection

Part Number: TPS22913

Hi team,

My customer evaluates the reverse current protection of TPS22913. In Vin side there is a 3.4V supply, and in Vout side there is a 4.5V supply. When Vin=3.4V, Vout=4.5V, EN is high, will it enable the protection and how long does it take?(10us?) When the protection enables, there is always a difference between Vout and Vin, and I wonder the maximum value of the difference. Besides, after the stable output of 4.5V supply, does it need to pull down EN? If pull down, whether the leak path inside the chip will be initiated, and how much leakage will be on VOUT at this time. If not pull down, Vout is consistently larger than Vin, will it cause any damage in long time running?

Best Regards,

Peter
