TPS61310: LED2 output current issue

Hi Sirs,

My customer tries to set the LED2 current to 700mA, but they only measure the 340mA current on LED2. How to fix this issue?

schematic:

F/W setting value:

static void StartTPS6105XFlash(U8 byIntensity)

{

          XBYTE[PG_GPIO_AL_CTRL0]  &= ~GPIO_AL2_DRIVING_HIGH;

          WriteTPS6105XReg(0x03, 0x73);

          WriteTPS6105XReg(0x05, 0x6F);

          XBYTE[PG_GPIO_AL_CTRL0] |= GPIO_AL0_DRIVING_HIGH;

          WriteTPS6105XReg(0x01, 0x1C); // LED 2 = 700mA

          WriteTPS6105XReg(0x02, 0x9F); // LED1/3 = 400mA

}
