HIP6020A DC-DC Converter Application Circuit

Figure 14 shows an application circuit of a power supply for

a microprocessor computer system. The power supply

provides the microprocessor core voltage (VOUT1), the AGP

bus voltage (VOUT2), the GTL bus voltage (VOUT3), and the

memory voltage (VOUT4) from +3.3V, +5VDC, and +12VDC.

For detailed information on a very similar circuit employing

an HIP6020, including a Bill-of-Materials and circuit board

description, see Application Note AN(TBD). Also see Intersil
