DATA SHEET
HOT-SWAP N+1 REDUNDANT XPHASE CONTROL IC
DESCRIPTION
The IR3510 Hot-Swap N+1 Redundant X-Phase Controller combines input isolation control for hot-
swappable application, X-Phase VRM/VRD control and output OR-ing control for N+1 redundant
application. It interfaces with microcontroller and X-Phase phase ICs to provide a full featured and
flexible solution for powering high-end CPUs and servers.
The IR3510 interfaces with system logic to receive “ENABLE”, “VSET” which is the analog reference
voltage for controlling VRM output voltage, constant current limit “OCPSET” and OVP limit “OVPSET”.
It feeds back to the system load current “IO”, VRM status “VRRDY”, OR-ing FETs status “ORING” and
input fault “IOCD”.
The IR3510 works with existing X-Phase phase ICs to provide a full featured multiphase VRM control,
including soft-start, voltage regulation, constant current limit, remote sense and open sense leads
protection.
The IR3510 continuously monitors the 12V input current and VRM output voltage. Once the input
current exceeds the programmable threshold, it goes to current limit mode and turn off the input FETs
when the OC delay times out. It immediately turns off the input FETs when an OV condition is detected
on the VRM output. It also has UVLO for both the 12V input and the supply voltage to the VRM.
The IR3510 has built-in OR-ing control function for N+1 redundant application. When the VRM output
voltage is higher than the output voltage bus, it turns on the OR-ing FETs; When the VRM output is
sinking current from the output voltage bus, it turns off the OR-ing FETs.
