LT1054/LT1054L  
Switched-Capacitor Voltage  
Converter with Regulator  
FEATURES  
DESCRIPTION  
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  
output currents. Total voltage loss at 100mA output current  
is typically 1.1V. This holds true over the full supply voltage  
range of 3.5V to 15V. Quiescent current is typically 2.5mA.  
■ꢀ  
Output Current: 100mA (LT1054)  
125mA (LT1054L)  
■
Reference and Error Amplifier for Regulation  
■
Low Loss: 1.1V at 100mA  
■
Operating Range:3.5V to 15V (LT1054)  
3.5V to 7V (LT1054L)  
■
External Shutdown  
■
External Oscillator Synchronization  
■
Can Be Paralleled  
The LT1054 also provides regulation, a feature not previ-  
ouslyavailableinswitched-capacitorvoltageconverters.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.  
Pin Compatible with the LTC®1044/ICL7660  
■
■
Available in SW16 and SO-8 Packages  
APPLICATIONS  
■
Voltage Inverter  
■
Voltage Regulator  
The internal oscillator of the LT1054 runs at a nominal  
frequency of 25kHz. The oscillator pin can be used to ad-  
just the switching frequency or to externally synchronize  
the LT1054.

Negative Voltage Doubler  
Positive Voltage Doubler
