ISL6522 DC-DC Converter Application
Circuit
Figure 11 shows a DC-DC converter circuit for a
microprocessor application, originally designed to employ
the HIP6006 controller. Given the similarities between the
HIP6006 and ISL6522 controllers, the circuit can be
implemented using the ISL6522 controller without any
modifications. Detailed information on the circuit, including a
complete bill of materials and circuit board description, can
be found in Application Note AN9722. See Intersil’s home
page on the web: http://www.intersil.com.
