What are the key features of LTC1550LCMS8-2#PBF?
- Inverted charge pump output delivering regulated -2 V from a 2.7 V to 5.25 V positive input supply
- 20 mA output current capability suitable for LCD bias, op-amp biasing, and small analog circuit needs
- Wide input range of 2.7 V to 5.25 V accommodates both 3.3 V and 5 V system power rails
- Compact 8-pin MSOP package minimizes board area in space-constrained portable and battery-powered designs
What is LTC1550LCMS8-2#PBF used for?
The LTC1550LCMS8-2#PBF is used in portable devices and battery-powered systems that require a small negative supply voltage for LCD panel biasing, analog switch control, or op-amp operation from a single positive rail. Its 2.7 V minimum input voltage supports 3.3 V powered systems common in microcontroller-based designs and handheld instruments. The charge pump approach eliminates the need for inductors, simplifying EMI management and PCB layout.

Frequently Asked Questions
What output voltage and current does LTC1550LCMS8-2#PBF provide for negative rail generation?
The LTC1550LCMS8-2#PBF generates a regulated -2 V output with up to 20 mA current capacity, sufficient for LCD bias voltage generation, op-amp negative supply rails, and analog switch biasing in portable systems powered from 2.7 V to 5.25 V positive rails.
How does LTC1550LCMS8-2#PBF simplify single-supply system designs requiring a negative voltage?
By inverting a 2.7 V to 5.25 V input to produce -2 V at 20 mA using a switched-capacitor charge pump with no inductors, the LTC1550LCMS8-2#PBF eliminates the need for a separate negative supply rail, reducing BOM size and avoiding inductor-related EMI issues in battery-powered handheld and sensor devices.
For which portable product categories is LTC1550LCMS8-2#PBF most commonly selected?
The LTC1550LCMS8-2#PBF is frequently used in handheld instruments, portable medical devices, and consumer electronics requiring a -2 V bias from a 3.3 V or 5 V bus, particularly where LCD panel controllers or audio op-amps need a small negative supply and board space is limited to the 8-pin MSOP footprint.
What distinguishes LTC1550LCMS8-2#PBF from a boost converter when generating negative voltages?
Unlike a boost converter that requires an inductor and complex layout to generate negative voltages, the LTC1550LCMS8-2#PBF uses a capacitor-based switched-capacitor inverter, producing a regulated -2 V output with only two small flying capacitors and no magnetic components, enabling a simpler, lower-noise PCB design in the compact 8-pin MSOP package.
