description/ordering information
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
adaptive-switch
drive
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.
scheme
optimizes
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
μ
A.
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

characterized for operation over a free-air temperature range of 40
