HIP6019 DC-DC Converter Application Circuit
Figure 15 shows an application circuit of a power supply for
a microprocessor computer system. The power supply
provides the microprocessor core voltage (VOUT1), the I/O
voltage (VOUT2), the GTL bus voltage (VOUT3) and clock
generator voltage (VOUT4) from +5VDC and +12VDC. For
detailed information on the circuit, including a Bill-of-
Materials and circuit board description, see Application Note
AN9800. Also see Intersil’s web page
