3VSB regulator
–Support Single or Dual mode select by PLED0/3VDLDEC#(Pin47)
–Single mode : Used one MOS regulate from 5VSB to 3VSB
–Dual mode : Used two MOS when S3 or S5 state standby MOS regulate from 5VSB to 3VSB,When S0 state turn on VCC3 MOS to 3VSB
Provide PLED0,PLED1 support S0,S1,S3,S5,under voltage indicator:
–Under voltage issue PLED0 and PLED1 flash by turns about 1/4Hz (If this condition occur system can’t power on unless plug AC power core)作者: 逸风 时间: 2010-6-4 22:19
