HIP6015 DC-DC Converter Application Circuit

Figure 11 shows an application circuit of a DC-DC Converter

for an Intel Pentium Pro microprocessor. Detailed

information on the circuit, including a complete

Bill-of-Materials and circuit board description, can be found

in application note AN9706. Although the Application Note

details the HIP6005, the same evaluation platform can be

used to evaluate the HIP6015. Intersil AnswerFAX (321-724-
