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 3.3V
DUAL
voltage (V
OUT1
), the RDRAM 2.5V
MEM
memory voltage
(V
OUT2
), and the 5V
DUAL
voltage (V
OUT3
) from +3.3V, +5V,
+5VSB, and +12VDC ATX supply outputs. For systems
employing SDRAM memory, replace R1 with 10k
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.
