    Hi Sophia,

    Feedback regarding the schematic:

    • Please ensure Cref (PC1) and Cint_ldo (PC4) meet their datasheet requirements across tolerance, temperature, and DC bias. 
    • VIN, VINP, and boost input decoupling capacitors (PC5, PC6, PC8118, PC7986, PC8117) are recommended to be rated for 10 V.
    • It is recommended to populate PC8118. 
    • Inverting buck-boost inductor (PL6506) must be 4.7 uH. See the device datasheet for recommendations. 
    • VCOM output capacitor is recommended to be rated for 10 V. 
    • Using alternative diodes from the EVM/datasheet may impact efficiency. 
    • Why does the customer have the option to pull-up VEE_FB and TS to VREF?
    • Why does the customer have the option to pull-up pin38 to VGH?

    Thanks,

    Gerard
