The LT®1054 is a monolithic, bipolar, switched-capacitor  
voltage converter and regulator. The LT1054 provides  
higher output current than previously available converters  
with significantly lower voltage losses. An adaptive switch  
driver scheme optimizes efficiency over a wide range of  
outputcurrents. Total voltagelossat100mAoutputcurrent  
is typically 1.1V. This holds true over the full supply voltage  
range of 3.5V to 15V. Quiescent current is typically 2.5mA.

External Oscillator Synchronization  
Can Be Paralleled  
The LT1054 also provides regulation, a feature not previ-  
ously available in switched-capacitor voltage converters.  
By adding an external resistive divider a regulated output  
can be obtained. This output will be regulated against  
changes in both input voltage and output current. The  
LT1054 can also be shut down by grounding the feedback  
pin. Supply current in shutdown is less than 100µA.
