IRU3034 & (PbF)
8-PIN PWM SWITCHER CONTROLLER IC WITH CURRENT LIMITING DESCRIPTION
The IRU3034 IC provides a low cost switching controller with true short circuit protection all in a compact 8-pin surface mount package, providing a low cost switching solution for dual supply processor applications that require switching
regulator for the 3.
3V supply such as the applications with AGP on-board.
Typically in these applications, a dual supply
regulator converts 5V to 3.
3V for I/O supply and a jumper programmable supply of 1.
25V to 3.
5V for Core supply.
The IC uses an internal
regulator generated from the 12V supply to power the controller as well as the 12V supply to...
