TPS61310: Flash mode setting

Part Number: TPS61310

Hi 

we are using TPS61310 in 400mA, Flash mode. Below is our setting, however the turn on time is very short (less than 1 ms), the waveform captured as below . Can you help review how to make the turn on time longer ? 

           WriteTPS6105XReg(0x01, 0x90);

          WriteTPS6105XReg(0x02, 0x9F);

          WriteTPS6105XReg(0x03, 0xFF);

          WriteTPS6105XReg(0x05, 0x87);
