HIGHLY EFFICIENT INTEGRATED  
SYNCHRONOUS BUCK REGULATOR FOR DDR APPLICATIONS  
Features  
Description  
The IR3831 SupIRBuckTM is an easy-to-use, fully  
integrated and highly efficient DC/DC regulator.  
The MOSFETS co-packaged with the on-chip  
PWM controller make IR3831 a space-efficient  
solution, providing accurate power delivery for  
DDR memory applications.

PGood output  
IR3831 is configured to generate termination  
voltage (VTT) for DDR memory applications.  
Programmable Soft-Start  
IR3831 offers programmability of start up time,  
switching frequency and current limit while  
operating in wide input and output voltage range.  
Enable Input with Voltage Monitoring Capability  
Enhanced Pre-Bias Start-up  
Vp input for DDR Tracking applications  
-40oC to 125oC operating junction temperature  
Thermal Protection  
The switching frequency is programmable from  
250kHz to 1.5MHz for an optimum solution.  
It also features important protection functions,  
such as Pre-Bias startup, hiccup current limit and  
thermal shutdown to give required system level  
security in the event of fault conditions.
