Description  
MARKING DIAGRAM  
Designed for use in battery−powered applications, the FAN2001/  
FAN2002 is a high−efficiency, low−noise synchronous PWM current  
mode and Pulse Skip (Power Save) mode dc−dc converter. It can  
provide up to 1 A of output current over a wide input range from 2.5 V  
to 5.5 V. The output voltage can be externally adjusted over a wide  
range of 0.8 V to 5.5 V by means of an external voltage divider.  
At moderate and light loads, pulse skipping modulation is used.  
Dynamic voltage positioning is applied, and the output voltage is  
shifted 0.8% above nominal value for increased headroom during load  
transients. At higher loads the system automatically switches over to  
current mode PWM control, operating at 1.3 MHz. A current mode  
control loop with fast transient response ensures excellent line and  
load regulation. To achieve high efficiency and ensure long battery  
life, the quiescent current is reduced to 25 mA in Power Save mode,  
and the supply current drops below 1 mA in shut−down mode. The  
FAN2001/FAN2002 is available in a 3x3 mm 6−lead MLP package.
