Preliminary  
APE2903  
MICROPOWER VFM STEP-UP DC/DC CONVERTER  
FEATURES  
DESCRIPTION  
The APE2903 is a high efficiency VFM Step-up DC/DC  
converter for small, low input voltage or battery powered  
systems with ultra low quiescent supply current. The  
Very Low Supply Current  
Regulated Output Voltage  
Wide Range of Output Voltage is Available from  
2.2V to 5.0V by 0.1V Steps  
APE2903 accept a positive input voltage from start-up  
voltage to VOUT and convert it to a higher output voltage in  
the 2.2 to 5V range.  
The APE2903 combine ultra low quiescent supply  
current and high efficiency to give maximum battery life. The  
high switching frequency and the internally limited peak  
inductor current permits the use of small, low cost inductors.  
Only three external components are needed an inductor a  
diode and an output capacitor.  
Output Voltage Accuracy ±5%  
Output Current up to 100mA  
Low Ripple and Low Noise  
Very Low Start-up Voltage  
High Efficiency (Vout = 5V TYP. 87%)  
Few External Components  
The APE2903 is suitable to be used in battery powered  
equipment where low noise, low ripple and ultra low supply  
current are required. The APE2903 is available in very small  
package: SOT-23, SOT-89 & SOT-23-5L.  
Internal Soft-Start  
Low Profile: SOT-23, SOT-89 & SOT-23-5L Pb-Free  
Typical applications are pagers, cameras & video  
camera, cellular telephones, wireless telephones, palmtop  
computer, battery backup supplies, battery powered  
equipment.
