Frequently Asked Questions
What input voltage range does the LTC1044AIS8#PBF support for switched-capacitor conversion?
The LTC1044AIS8#PBF operates from 1.5V to 12V input, covering single alkaline cells at 1.5V through 9V battery packs and 12V regulated supplies. This wide range makes it versatile for both battery-powered portable instruments and fixed-supply bench equipment. The device generates inverted or doubled output voltages up to 13V using external capacitors without any inductors.
How does the LTC1044AIS8#PBF eliminate inductors in negative rail generation compared to buck-boost converters?
The LTC1044AIS8#PBF uses a switched-capacitor charge pump topology that transfers charge between external capacitors to invert or double the input voltage, removing any magnetic components from the power path. This reduces PCB area, eliminates inductor EMI, and simplifies layout compared to inductor-based buck-boost converters. External capacitors of a few microfarads are sufficient to achieve output currents in the milliamp range from a 5V or 12V supply.
Which circuit configurations can the LTC1044AIS8#PBF implement with only a few external components?
With two external capacitors, the LTC1044AIS8#PBF can be configured as a voltage inverter producing a negative output equal to the negative of the input voltage, or as a voltage doubler delivering approximately twice the input voltage up to 13V. These configurations are used for generating ±5V dual rails from a single 5V supply, biasing op-amps in single-supply systems, and powering RS-232 drivers that require negative voltages.
What output current capability should designers expect from the LTC1044AIS8#PBF at 5V input?
At a 5V nominal input, the LTC1044AIS8#PBF delivers output currents in the range of tens of milliamps depending on external capacitor values and load regulation requirements. Larger external capacitors (above 10 µF) improve output current capacity and reduce voltage droop under load. This current level suits op-amp bias networks, reference circuits, and small analog signal conditioning loads that do not require high-power negative rails.
