HIP6502 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

3.3VDUAL/3.3VSB voltage (VOUT3), the SDRAM 3.3VMEM

voltage (VOUT1), the RDRAM 2.5VMEM memory voltage

(VOUT2), the 2.5VCLK clock voltage (VOUT4), and the

5VDUAL voltage (VOUT5) 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.
