HIP6012 DC-DC Converter Application Circuit
The figure below shows a DC-DC converter circuit for a
microprocessor application, originally designed to employ
the HIP6006 controller. Given the similarities between the
HIP6006 and HIP6012 controllers, the circuit can be
implemented using the HIP6012 controller without any
modifications. However, given the expanded reference
voltage tolerance range, the HIP6012-based converter may
