Voltage Distribution(3)
F15V and Sub-Voltages Circuit Explanation
The F15V from the power supply is connected to pins 5/6 of connector A6 of the A board.
After passing the pin 5/6 of A6 connector, F15V is applied to 6 components.
Application Specific IC(IC5000), the voltage regulators IC8704,IC8705, IC8100, IC8101 and IC9803.
These ICs above except IC5000, are activated by DCDCEN, DCDCEN2, P_OOPCTRL11 and P_TCON9.
After receiving the DCDCEN, follow ICs convert F15V to lower voltage.
■IC8704 convert F15V to SUB5V.
The SUB5V from IC8704 is applied to IC9804/8602/8603/8605/5709/5716/5702 and IC5000.
■IC8705 convert F15V to SUB3.3V
The SUB3.3V from IC8705 is applied to IC4900/4901/2000/8900/8901/5704/5010 and IC9005.
■IC8100 convert F15V to SUB1.5V and supply to only IC8000.
■IC8101 convert F15V to SUB1.2V and supply to IC8000 and IC8200/8201/8202 DDR3.
■IC5000 convert F15V to SUB9V and supply to only IC3300.
■IC9803 convert F15V to P1.2V and supply to only IC9300.
