• Manufacturer Part Number: iru3033
• Description: 8-pin Pwm Switcher And Linear Controller Ic
• Manufacturer: International Rectifier Corp.

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.
