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 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.
