DESCRIPTION
The IRU3007 controller IC is specifically designed to meet
Intel specification for Pentium IImicroprocessor 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 RDS(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.

PIN DESCRIPTION
Output driver for the high-side power MOSFET for the I/O supply.
This pin is connected to the Source of the power MOSFET for the I/O supply and it
provides the negative sensing for the internal current sensing circuitry.
This pin selects a range of output voltages for the DAC. When in the LO state the range
is 1.3V to 2.05V and when it switches to HI state the range is 2.0V to 3.5V. This pin is
TTL compatible that realizes a logic “1” as either HI or Open. When left open, this pin is
pulled up internally by a 27KV resistor to 5V supply.
MSB input to the DAC that programs the output voltage. This pin is TTL compatible that
realizes a logic “1” as either HI or Open. When left open, this pin is pulled up internally by
a 27KV resistor to 5V supply.
Input to the DAC that programs the output voltage. This pin is TTL compatible that real-
izes a logic “1” as either HI or Open. When left open, this pin is pulled up internally by a
27KV resistor to 5V supply.
Input to the DAC that programs the output voltage. This pin is TTL compatible that real-
izes a logic “1” as either HI or Open. When left open, this pin is pulled up internally by a
27KV resistor to 5V supply.
LSB input to the DAC that programs the output voltage. This pin is TTL compatible that
realizes a logic “1” as either HI or Open. When left open, this pin is pulled up internally by
a 27KV resistor to 5V supply.
This pin is an open collector output that switches LO when any of the outputs are outside
of the specified under voltage trip point. It also switches low when VSEN1 pin is more than
10% above the DAC voltage setting.
This pin is connected to the Drain of the power MOSFET of the I/O supply and it provides
the positive sensing for the internal current sensing circuitry. An external resistor pro-
grams the CS threshold depending on the RDS of the power MOSFET. An external ca-
pacitor is placed in parallel with the programming resistor to provide high frequency noise
filtering.
