HIP6004A 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 AN9672. Although the Application Note

details the HIP6004, the same evaluation platform can be

used to evaluate the HIP6004A. Intersil AnswerFAX (407-
