HIP6028 DC-DC Converter Application Circuit
Figure 16 shows an application circuit of a power supply for
a microprocessor computer system. The power supply
provides the microprocessor core voltage (VOUT1), the GTL
bus voltage (VOUT3) and clock generator voltage (VOUT2)
from +3.3VDC, +5VDC and +12VDC. For detailed information
on the circuit, including a Bill-of-Materials and circuit board
description, see Application Note AN9833. Also see Intersil’s
web page (http://www.intersil.com) or Intersil AnswerFAX
(407-724-7800) document # 99833 for the latest information.
