HIP6500B Application Circuit
Figure 14 shows an application circuit of an ACPI-
sanctioned power management system for a microprocessor
computer system. The power supply provides the 3.3V
voltage (V
RDRAM 2.5VMEM memory voltage (V
clock voltage (V
from +3.3V, +5VSB, and +12VDC ATX supply outputs. For
systems employing SDRAM memory, replace R1 with 10k
