FAN5029  
8-Bit Programmable 2- to 5-Phase Synchronous Buck Controller  
Description  
Features  
The FAN5029 is  
a multi-phase buck switching  
• Selectable 2-, 3-, 4-, or 5-phase operation at up to  
regulator controller optimized to convert a 12V input  
supply to the processor core voltage required by high-  
performance Intel® processors. It has an internal 8-bit  
DAC that converts a digital voltage identification (VID)  
code that is sent from the processor to set the output  
voltage between 0.5V and 1.6V. It outputs a PWM to  
external MOSFET drivers that, in turn, drive the  
switching power MOSFETs. The switching frequency  
of the design is programmable by a single resistor  
value and the number of phases can be programmed  
to support 2-, 3-, 4-, or 5-phase applications.  
1MHz per phase  
• ±7.7mV worst-case differential sensing error  
• Active current balancing between the output phases  
• Power good and crowbar blanking supports on-the-  
fly VID code changes  
• Selectable VR10 extended (7-bit) and VR11 (8-bit)  
VID tables  
• Programmable short-circuit protection and latch-off  
delay  
• Programmable soft start ramp  
The FAN5029 also includes programmable no-load  
offset and droop functions to adjust the output voltage  
as a function of the load current, as required by the  
Intel specifications. The FAN5029 also provides an  
accurate and reliable short-circuit protection function  
with an adjustable over-current set point.  
Applications  
• Desktop PC/Server processor power supplies for  
existing and next generation Intel processors  
• VRM modules products  
The FAN5029 is specified over the extended  
commercial temperature range of 0°C to +85°C and is  
available in a 40-lead MLP package.  
Part Numbers  
• FAN5029MPX is not for new designs.  
• The FAN5029MPX_NAAC238 replaces the  
FAN5029MPX and is compatible with all VR10 and  
VR11 processors.
