HIP6016
HIP6016 DC-DC Converter Application Circuit
Figure 15 shows an application circuit of a power supply for
a microprocessor computer system. The power supply
provides the microprocessor core voltage (VOUT1), the 1.5V
GTL bus voltage (VOUT3) and the 2.5V clock generator
voltage (VOUT2) from +3.3VDC, +5VDC and +12VDC. For
