HIP6004B 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 HIP6004B.
