... DAC TT_GMCH/CPU V is capable of sourcing and sinking current. TT_GMCH/CPU A more complete description of the ISL6548A can be found in the datasheet[1]. The ISL6506 controls the 5VDUAL and 3.3VDUAL rails. There are three versions of the ISL6506. The version required will depend on whether 5V Dual is required to be active during S4/S5 ...

ISL6548A_6506EVAL1Z STATES S3 SWITCH S5 SWITCH SLEEP STATE ACTIVE ACTIVE S0 (Active) S3 ACTIVE S3 ACTIVE both the S3 and S5 switches are thrown to S3 and S5, respectively, the board will default state. If the board is in either sleep state, the ATX supply is put into standby mode, where only the 5VSBY rail is active ...

... HIGH, the PCIRST# signal from the ICH asserts HIGH. When PCIRST# asserts HIGH, bus traffic resumes and the system is awake. The ISL6506 and ISL6548A chipset bring all the ACPI rails under their control into regulation between time T3 and T4. V This timing assures, even with minimum specified system ...

... GMCH up until the V entering a sleep state, the V the V GMCH ramp down. A circuit was included on the ISL6548A evaluation board that will keep a 0.7V differential between the V V rails until the V DAC also discharge the V a sleep state. This circuit is shown in Figure 7. During start- FIGURE 7 ...
