FAN5182 — Adjustable Output, 1-, 2-, or 3-Phase  
Synchronous Buck Controller  
Features  
Description  
The FAN5182 is  
a
highly efficient, multiphase,  
ƒ
Selectable 1-, 2-, or 3-Phase Operation at up to  
1MHz per 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  
ƒ
ƒ
Accuracy: 1%  
(POL) applications. It uses  
a
multi-loop PWM  
Externally Adjustable 0.8V to 5V Output from a  
12V Supply  
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.  
ƒ
Logic-Level PWM Outputs for Interface to External  
High-Power Drivers  
ƒ
ƒ
ƒ
Active Current Balancing Between all Phases  
Built-in Power-Good / Crowbar Functions  
Programmable Over-Current Protection with  
Adjustable Latch-Off Delay  
The FAN5182 provides accurate and reliable over-  
current protection and adjustable current limiting.  
The FAN5182 is specified over the commercial  
temperature range of 0°C to +85°C and is available in a  
20-lead Quarter-Size Outline Package (QSOP).
