AP1603  
Step-Up DC/DC Converter  
„ Features  
„ General Description  
-A Guaranteed Start-Up from less than 0.9 V.  
-High Efficiency.  
The AP1603 is a high efficiency step-up DC/DC  
converter for applications using 1 to 2 NiMH battery  
cells. Only three external components are required  
to deliver a fixed output voltage of 3.3V. The  
AP1603 starts up from less than 0.9V input with  
1mA load. Pulse Frequency Modulation scheme  
brings optimized performance for applications with  
light output loading and low input voltages. The  
output ripple and noise are lower compared with the  
circuits operating in PSM mode.  
-Low Quiescent Current.  
-Less Number of External Components needed.  
-Low Ripple and Low Noise.  
-Space Saving Pb-Free Packages: SOT23-6  
„ Applications  
The PFM control circuit operating in 150KHz (max.)  
switching rate results in smaller passive  
components. The space saving SOT23-6 packages  
make the AP1603 an ideal choice of DC/DC  
converter for space conscious applications, like  
pagers, electronic cameras, and wireless  
microphones.  
-Pagers.  
-Cameras.  
-Wireless Microphones.  
-Pocket Organizers.  
-Battery Backup Suppliers.  
-Portable Instruments.
