Features  
Description  
• High power switch-mode DC-DC controller can provide  
in excess of 13A  
• Output voltage adjustable from 1.2V to 3.6V  
• 85% efficiency  
• Cumulative accuracy < 3% over line, load, and  
temperature variations  
• Overvoltage and short circuit protection  
• Built-in soft start  
The FAN5037 is a high power, switch-mode DC-DC control-  
ler that provides efficient power for all low-voltage applica-  
tions. This controller has a built-in Soft Start feature which  
offers system protection during power-up by reducing both  
inrush current and output overshoot. When combined with  
the appropriate external circuitry, the FAN5037 can deliver  
load currents as high as 13A at efficiencies as high as 88%.  
The FAN5037 can generate output voltages from 1.2V up to  
3.6V using external resistors.  
• No overshoot at turn-on  
The FAN5037 is designed to operate in a constant on-time  
control mode under all load conditions. Its accurate low TC  
reference eliminates the need for precision external compo-  
nents in order to achieve the tight tolerance voltage regula-  
tion required by many applications. Short circuit current  
protection is provided through the use of a current sense  
resistor, while overvoltage protection is provided internally.  
Applications  
• I/O and AGP power for desktop computers  
• High efficiency power for ASICs  
• High efficiency power for DSPs  
• Adjustable step-down power supplies
