TYPICAL APPLICATION
5V
DESCRIPTION
The IRU3007 controller IC is specifically designed to meet
Intel specification for Pentium II
microprocessor ap-
plications as well as the next generation of P6 family
processors. The IRU3007 provides a single chip control-
ler IC for the Vcore, LDO controller for GTL+ and an
internal 200mA regulator for clock supply which are re-
quired for the Pentium II applications. It also contains a
switching controller to convert 5V to 3.3V regulator for
on-board applications that uses either AT type power
supply or is desired not to rely on the ATX power supply’s
3.3V output. These devices feature a patented topology
that in combination with a few external components, as
shown in the typical application circuit, will provide in
excess of 14A of output current for an on-board DC/DC
converter while automatically providing the right output
voltage via the 5-bit internal DAC. The IRU3007 also fea-
tures, loss-less current sensing for both switchers by
using the R
DS(on)
of the high-side power MOSFET as the
sensing resistor, internal current limiting for the clock
supply, a Power Good window comparator that switches
its open collector output low when any one of the out-
puts is outside of a pre-programmed window. Other fea-
tures of the device are: Under-Voltage Lockout for both
5V and 12V supplies, an external programmable soft-
start function, programming the oscillator frequency via
an external resistor, Over-Voltage Protection (OVP) cir-
cuitry for both switcher outputs and an internal thermal
shutdown.
