HIP6013 DC-DC Converter Application Circuit

The figure below shows a DC-DC converter circuit for a

microprocessor application, originally designed to employ the

HIP6007 controller. Given the similarities between the HIP6007

and HIP6013 controllers, the circuit can be implemented using

the HIP6013 controller without any modifications. However,

given the expanded reference voltage tolerance range, the

HIP6013-based converter may require additional output

capacitance. 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.
