2.2 System Power-On/Power-Off

VDD_LCD is a 5V power input from the external processor board. It must be converted to the 3.3V VLCD_3V3 power rail for the EEPROM memory and the LVDS display.

The MIC23150 is implemented, which is a synchronous Buck regulator with a HyperLight Load® mode. HyperLight Load technology provides high efficiency at light loads and ultra-fast transient response, making it suitable for supplying processor core voltages.
