PF3000 power budget

We are using PF3000 to drive i.MX6UL. I am using PF3000 SW1A switcher to drive 3.3V power rails of the CPU, which includes NVCC_LCDIF,NVCC_ENET, NVCC_NAND, NVCC_GPIO, NVCC_SD, NVCC_CSI, NVCC_UART.

Out of this we are not using LCD, NAND interface. Based on the calculations done with the help of datasheet, the overall current consumption comes out to be around 100mA, while SW1A can  provide current upto 1A.

While in EVK some interface used work on 1.8V(UART and CSI). So I am worried as I am using all interfaces on 3.3V and SW1A can drive the required current to the CPU or not.

Let me know your comments on this.
