HIP6501A Application Circuit
Figure 13 shows an application circuit of an ACPI-compliant
power management system for a microprocessor computer
system. The power supply provides the PCI 3.3VDUAL
voltage (VOUT1), the RDRAM 2.5VMEM memory voltage
(VOUT2), and the 5VDUAL voltage (VOUT3) from +3.3V, +5V,
+5VSB, and +12VDC ATX supply outputs. For systems
employing SDRAM memory, replace R1 with 10k
Ω and Q1
with an HUF76113SK8. Q4 can also be a PNP, such as an
MMBT2907AL. For detailed information on the circuit,
including a Bill-of-Materials and circuit board description,
see Application Note AN9846.
