PENTIUM CORE SUPPLY APPLICATION PARTS LIST
(IRU3034 and IRU3033 Dual Layout) Low Cost 4-Bit VID
*R4 is a parallel combination of R4A and R4B.
Note: 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.
