Multiple Linear Power Controller With ACPI Control Interface

The ISL6504 and ISL6504A complement other power building blocks (voltage regulators) in ACPI-compliant designs for Microprocessor and computer applications. The IC integrates three linear controllers Regulators switching, monitoring and control functions into a 16-pin wide-body SOIC or 20-pin QFN 6x6 package. The ISL6504 ISL6504A operating mode (active outputs or sleep outputs) is selectable through two digital control pins, S3 and S5.
One linear controller generates the 3.3VDUAL/3.3VSB voltage plane from the ATX supplys 5VSB output, powering the south bridge and the PCI slots through an external NPN pass Transistor during sleep states (S3, S4/S5). In active state (during S0 and S1/S2), the 3.3VDUAL/3.3VSB linear Regulator uses an external N-channel pass MOSFET to connect the outputs directly to the 3.3V input supplied by an ATX power supply, for minimal losses. A controller powers up the 5VDUAL
plane by switching in the ATX 5V output through an NMOS Transistor in active states, or by switching in the ATX 5VSB through a PMOS (or PNP) Transistor in S3 sleep state. In S4/S5 sleep states, the ISL6504 5VDUAL output is shut down. In the ISL6504A the 5VDUAL output stays on during S4/S5 sleep states. This is the only difference between the two parts; see Table 1.
An internal linear Regulator supplies the 1.2V for the voltage identification circuitry (VID) only during active states (S0 and S1/S2), and uses the 3V3 pin as input source for its internal pass element. Another internal Regulator outputs a 1.5VSB chip-set standby supply, which uses the 3V3DL pin as input source for its internal pass element. The 3.3VDUAL/3.3VSB and 1.5VSB outputs are active for as long as the ATX 5VSB voltage is applied to the chip.
