The LT1054 is a bipolar, switched-capacitor  
voltage converter with regulator. It provides higher  
output current and significantly lower voltage  
losses than previously available converters. An  
NC  
NC  
adaptive-switch  
drive  
scheme  
optimizes  
efficiency over a wide range of output currents.  
Total voltage drop at 100-mA output current  
typically is 1.1 V. This applies to the full  
supply-voltage range of 3.5 V to 15 V. Quiescent  
current typically is 2.5 mA.  
NC − No internal connection  
The LT1054 also provides regulation, a feature previously not available in switched-capacitor voltage  
converters. By adding an external resistive divider, a regulated output can be obtained. This output is regulated  
against changes in both input voltage and output current. The LT1054 also can be shut down by grounding the  
feedback terminal. Supply current in shutdown typically is 100 μA.  
The internal oscillator of the LT1054 runs at a nominal frequency of 25 kHz. The oscillator terminal can be used  
to adjust the switching frequency or to externally synchronize the LT1054.  
The LT1054C is characterized for operation over a free-air temperature range of 0°C to 70°C. The LT1054I is  
characterized for operation over a free-air temperature range of −40°C to 85°C.
