Automotive 4-Channel TFT-LCD Power Supply with VCOM Buffer and ASIL B Features using MAX25222.
The MAX25222/MAX25222C are 4-channel TFT-LCD power ICs that provide symmetrical positive AVDD and negative NAVDD supplies as well as VGON and VGOFF gate supplies. In addition, a VCOM buffer with output voltage range above and below ground and a temperature measurement block are integrated.
Schematic is designed in Easy EDA and references have been taken from datasheet.
PCB is design is of 40 layers. References are taken from datasheet but it is highly recommended to consult datasheet for EMI considerations.
