8-Bit Programmable 2- to 5-Phase  
Synchronous Buck Controller  
ADP3189  
This device uses a multi-mode PWM architecture to drive the  
logic-level outputs at a programmable switching frequency that  
can be optimized for VR size and efficiency. The phase relation-  
ship of the output signals can be programmed to provide 2-, 3-,  
4-, or 5-phase operation, allowing for the construction of up to  
five complementary buck switching stages.  
FEATURES  
Selectable 2-, 3-, 4-, or 5-phase operation at up  
to 1 MHz per phase  
±±7± ꢀV worst-case differential sensing error over  
teꢀperature  
Logic-level PWM outputs for interface to external  
high-power drivers  
The ADP3189 also includes programmable no-load offset and  
slope functions to adjust the output voltage as a function of the  
load current, so it is optimally positioned for a system transient.  
The ADP3189 also provides accurate and reliable short-circuit  
protection, adjustable current limiting, and a delayed power  
good output that accommodates on-the-fly output voltage  
changes requested by the CPU.  
Active current balancing between all output phases  
Built-in power good/crowbar blanking supports on-the-fly  
VID code changes  
Digitally prograꢀꢀable 075 V to 176 V output— supports  
both VR107x and VR11 specifications  
Prograꢀꢀable short-circuit protection with prograꢀꢀable  
latch-off delay  
ADP3189 is specified over the extended commercial tem-  
perature range of 0°C to +85°C and is available in a  
40-lead LFCSP package.  
APPLICATIONS  
Desktop PC power supplies for  
Next generation Intel® processors  
VRM ꢀodules  
1 Protected by U.S. Patent Number 6,683,441; others pending.  
GENERAL DESCRIPTION  
The ADP31891 is a highly efficient multi-phase synchronous  
buck switching regulator controller optimized for converting a  
12 V main supply into the core supply voltage required by high  
performance Intel processors. It uses an internal 8-bit DAC to  
read a voltage identification (VID) code directly from the  
processor, which is used to set the output voltage between 0.5 V  
and 1.6 V.
