8-pin Pwm Switcher And Linear Controller Ic - International Rectifier

The IRU3033 IC combines a switching controller and a linear Regulator controller all in a compact 8-pin surface mount package, providing a total solution for dual sup- ply processor applications such as an Intel P55C, AMD K6, as well as Cyrix 6X86L and the M2 proces- sors. Typically in these applications a dual supply regu- lator converts 5V to 3.3V for I/O supply and a jumper programmable supply of 1.25V to 3.5V for Core supply. The linear Regulator controller portion in the IRU3033 is a programmable controller allowing flexibility for the I/O Regulator and has a minimum of 50mA drive current ca- pability designed to provide ample current for an exter- nal pass Transistor The IC uses an internal Regulator generated from the 12V supply to power the controller as well as the 12V supply to drive the Power MOSFET allowing a low cost N-Channel MOSFET Switch to be used. The IC also includes an error Comparator for fast transient response, a precise Voltage Reference for set- ting the output voltage as well as a direct drive of the MOSFET for the minimum part count.
