2/3/4 phase controller with embedded drivers for Intel VR11.1  
Data Brief  
Features  
■ Load transient boost LTB Technology™ to  
minimize the number of output capacitors  
■ 2 or 3-phase operation with internal driver  
■ 4-phase operation with external PWM driver  
signal  
VFQFPN48 7 mm x 7 mm  
(exposed pad)  
■ PSI input with programmable strategy  
■ Imon output  
■ 0.5 % output voltage accuracy  
Description  
■ 8 bit programmable output up to 1.60000 V -  
Intel VR11.1 DAC - backward compatible with  
VR10/VR11  
The device implements a two-to-four phases step-  
down controller with three integrated high current  
drivers in a compact 7x7 mm body package with  
exposed pad.  
■ Full differential current sense across inductor  
■ Differential remote voltage sensing  
■ Adjustable voltage offset  
Load transient boost LTB Technology™ reduces  
system cost by providing the fastest response to  
load transition therefore requiring less bulk and  
ceramic output capacitors to satisfy load transient  
requirements.  
■ LSLess startup to manage pre-biased output  
■ Feedback disconnection protection  
■ Preliminary over voltage protection  
■ Programmable over current protection  
■ Programmable over voltage pretection  
■ Adjustable switching frequency  
The device embeds VR11.x DACs: the output  
voltage ranges up to 1.60000 V managing D-VID  
with 0.5 % output voltage accuracy over line  
and temperature variations.  
■ SS_END and OUTEN signal  
The controller assures fast protection against load  
over current and under / over voltage (in this last  
case also before UVLO). Feedback disconnection  
prevents from damaging the load in case of  
disconnections in the system board.  
■ VFQFPN48 7 mm x 7 mm package with  
exposed pad  
Applications  
In case of over-current, the system works in  
constant current mode until UVP.  
■ High current VRM/VRD for desktop / server /  
workstation CPUs  
■ High density DC-DC converters
