IR3081A
DATA SHEET
XPHASE TM VR 10 CONTROL IC
DESCRIPTION
The IR3081A Control IC combined with an IR XPhase TM Phase IC provides a full featured and flexible way
to implement a complete VR 10 power solution. The “Control” IC provides overall system control and
interfaces with any number of “Phase ICs” which each drive and monitor a single phase of a multiphase
converter. The X Phase TM architecture results in a power supply that is smaller, less expensive, and easier
to design while providing higher efficiency than conventional approaches. The IR3081A is intended for
VRD 10 or VRM/EVRD 10 applications that use external VCCVID/VTT circuits.
The IR3081A is functionally equivalent to the IR3081, but incorporates the following modifications:
? Under Voltage Lockout start threshold increased from 9.1V to 9.7V (typical) and hysteresis increased
?
?
?
from 200mV to 800mV (typical).
Hysteresis (52mV typical) added to the SS/DEL comparator to prevent Power Good output chatter.
Over current discharge current increased from 6uA to 40uA (typical) to reduce the over current delay
time.
IIN pin precondition circuit added to disable current sharing in the phase ICs during soft start.
