HIP6017
HIP6017 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 (V_OUT1), the GTL
bus voltage (V_OUT3) and clock generator voltage (V_OUT2)
from +3.3VDC, +5V_DC and +12V_DC . 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 (http://www.intersil.com).
