APPLICATION PARTS LIST
5V to 3.3V for Pentium Application with AGP or Pentium II Application without ATX power supply Dual
mode Operation between Switching or Linear mode.
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.
