TYPICAL APPLICATION
DESCRIPTION
The IRU3055 is a 3-phase synchronous Buck controller
which provides high performance DC to DC converter for
high current applications.
The IRU3055 controller IC is specifically designed to meet
Intel and AMD specifications for the new microproces-
sor requiring low voltage and high current.
The IRU3055 features under-voltage lockout for both 5V
and 12V supplies, an external and programmable soft-
start function as well as programming the oscillator fre-
quency by using an external resistor.
Meets VRM 9.0 Specification
3-Phase Controller with On-Board MOSFET Driver
On-Board DAC programs the output voltage from
1.075V to 1.850V
Loss-less Short Circuit Protection
Programmable Frequency
Synchronous operation allows maximum efficiency
Minimum Part Count
Soft-Start
Power Good Function
Hiccup Mode Current Limit
