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.
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.
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.
The LT1054 is pin compatible with previous converters
such the LTC1044/ICL7660.
