IPM6210 DC-DC Converter Application Circuit
Figure 12 shows an application circuit of a power supply for
a notebook PC microprocessor system. The power supply
provides the microprocessor core voltage (V
CORE
), the I/O
voltage (V
I/O
) and the clock generator voltage (V
CLK
) from
+5.6-24V
DC
, +5V
DC
and +3.3V
DC
.
