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
