L6722  
3 Phase controller for DC/DC converters  
Features  
2A integrated gate drivers  
0.8V reference  
1% output voltage accuracy  
Adjustable reference offset  
VFQFPN36  
Precise current sharing and OCP across LS  
MOSFETS  
Constant over current protection  
Feedback disconnection  
Description  
L6722 implements a three-phase step-down  
controller with 120º phase-shift between each  
phase with integrated high-current drivers in a  
compact VFQFPN36 package with exposed pad.  
LSLESS allows managing pre-bias startup  
Preliminary of protection  
Oscillator internally fixed at 100kHz, externally  
L6722 manages output voltages down to 0.8V  
with 1% output voltage accuracy over line and  
temperature variations. Additional programmable  
offset can be added to the reference voltage with  
a single external resistor in order to perform  
margining tests.  
adjustable  
Power good  
Integrated remote sense buffer  
VFQFPN36 package with exposed pad  
Applications  
The controller assures fast protection against load  
over current and over / under voltage. In case of  
over-current the system works in Constant  
Current mode until UVP. Preliminary OVP allows  
full load protection in case of startup with failed  
HS. Feedback-disconnection protection prevents  
from damaging the load in case of misconnections  
in the remote sense. Pre-bias start-up is also  
managed thanks to LSLESS.  
Memory supply for server and workstation MBs  
High density DC / DC converters  
High current pol  
Combined use of DCR and RdsON current  
sensing assures precision in voltage positioning  
(by reading droop current across inductors DCR)  
and safe current sharing and OCP per each  
phase (by reading the current across LS RdsON).  
Droop function can be anyway disabled to  
perform precise and load-insensitive regulation.
