LT1054CP DIP8The LT1054CP 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 100mA output current typically is 1.1V. This applies to the full supply-voltage range of 3.5 to 15V. Quiescent current typically is 2.5mA. The LT1054CP 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 LT1054CP can also shut down by grounding the feedback terminal. Supply current in shutdown typically is 100µA. The internal oscillator of the LT1054CP runs at a nominal frequency of 25kHz., Low loss, 1.1V at 100mA, Reference and error amplifier for regulation, External shutdown, External oscillator synchronization, Devices can be paralleled, Pin-to-pin compatible with LTC1044/7660
