HIP6021 DC-DC Converter Application Circuit
Figure 12 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 the circuit, including a Bill-of-Materials
and circuit board description, see Application Note AN9836.
