HI,

It is suggested to assert EN after both V5 and VIN are well established:

1. V5 provide power to internal analog and gate driver circuit, if not well established, IC state is unknown, asserting EN will lead to un-predicted results
2. If Vin is too low, soft start will be affected

Hi Ito-san,

once both VIN & V5 are ready, EN can be asserted immediately
