Product Description

Description
The LT1054 device 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 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 can also shut down by grounding the feedback terminal. Supply current in shutdown typically is 100 μA.
Features
• Output Current, 100 mA
• Low Loss, 1.1 V at 100 mA
• Operating Range, 3.5 V to 15 V
• Reference and Error Amplifier for Regulation
• External Shutdown
• External Oscillator Synchronization
• Devices Can Be Paralleled
• Pin-to-Pin Compatible With the LTC1044/7660
Applications
• Industrial Communications (RS232)
• Data Acquisition Supply
• Voltage Inverters
• Voltage Regulators
• Negative Voltage Doublers
• Positive Voltage Doublers
