FAN5182  
Adjustable Output 1, 2, or 3-Phase Synchronous Buck  
Controller  
Features  
Description  
Selectable 1-, 2-, or 3-phase operation at up to 1MHz per  
phase  
The FAN5182 is a highly efficient multi-phase synchronous buck  
switching regulator controller optimized for converting a 12V  
main supply into a high-current low voltage supply for use in  
point-of-load (POL) applications. It uses a multi-loop PWM  
architecture to drive the logic-level outputs at a programmable  
switching frequency that can be optimized for regulator size and  
efficiency. The phase relationship of the output signals can be  
programmed to provide 1, 2, or 3-phase operation, allowing for  
construction of up to three complementary interleaved buck  
switching stages.  
2ꢀ Worst-case differential sensing error over temperature  
Externally adjustable 0.8V to 5V output from a 12V supply  
Logic-level PWM outputs for interface to external high-power  
drivers  
Active current balancing between all phases  
Built-in power-good/crowbar functions  
Programmable over current protection with adjustable latch-  
off delay  
The FAN5182 also provides accurate and reliable over-current  
protection and adjustable current limiting.  
Applications  
Auxiliary supplies  
FAN5182 is specified over the commercial temperature range of  
0°C to +85°C and is available in a 20-lead QSOP package.
