HIP6502B Application Circuit
Figure 11 shows an application circuit of an ACPI-
sanctioned power management system for a microprocessor
computer system. The power supply provides the
3.3V
DUAL
/3.3V
SB
voltage (V
OUT3
), the SDRAM 3.3V
MEM
voltage (V
OUT1
), the RDRAM 2.5V
MEM
memory voltage
(V
OUT2
), the 2.5V
CLK
clock voltage (V
OUT4
), and the
5V
DUAL
voltage (V
OUT5
) from +3.3V, +5VSB, +5V, and
+12VDC ATX supply outputs. 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 AN9862.
