FAN2001/FAN2002  
1A High-Efficiency Step-Down DC-DC Converter  
Features  
Description  
96% Efficiency, Synchronous Operation  
Adjustable Output Voltage Options from 0.8V to V  
2.5V to 5.5V Input Voltage Range  
Up to 1A Output Current  
Designed for use in battery-powered applications, the FAN2001/  
FAN2002 is a high-efficiency, low-noise synchronous PWM cur-  
rent mode and Pulse Skip (Power Save) mode DC-DC con-  
verter. It can provide up to 1A of output current over a wide input  
range from 2.5V to 5.5V. The output voltage can be externally  
adjusted over a wide range of 0.8V to 5.5V by means of an  
external voltage divider.  
IN  
Fixed Frequency 1.3MHz PWM Operation  
High Efficiency Power Save Mode  
100% Duty Cycle Low Dropout Operation  
Soft Start  
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 dur-  
ing 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 effi-  
ciency and ensure long battery life, the quiescent current is  
reduced to 25µA in Power Save mode, and the supply current  
drops below 1µA in shut-down mode. The FAN2001/FAN2002 is  
available in a 3x3mm 6-lead MLP package.  
Output Over-Voltage Protection  
Dynamic Output Voltage Positioning  
25µA Quiescent Current
