Figure 5 - The circuit in figure 4 is the application of the IRU3033 in a switching mode only. This circuit can be used
to generate a low cost 5V to 3.3V for either Pentium application with AGP socket or in Pentium II applications
where it is desirable to generate an accurate on board 3.3V supply.
TYPICAL APPLICATION
5V to 3.3V for Pentium application with AGP or Pentium II application
without ATX power supply switching mode operation.

Note 1:
For the applications where it is desirable to eliminate the heat sink, the IRL3103S for Q2 and
MBR1545CT for D2 in TO-263 packages with minimum of 1" square copper pad can be used.
