Switched-Capacitor Voltage Converters With Regulator

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 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.
The LT1054 also provides regulation, a feature not previously 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 is typically 100 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 0C to 70C. The LT1054I is characterized for operation over a free-air temperature range of -40C to 85C.
